AEO-Certification
Customers of UTP Maintenance, with its headquarters in
Bad Krozingen and Seneffe, can now enjoy an even more
reliable supply chain and streamlined customs clearing.
With the award of the AEO-F certificate (Authorized Economic Operator), valid from December 27, 2012, the Bielefeld chief customs office has acknowledged Boehler Schweisstechnik
Deutschland GmbH’s secure and reliable handling of international trade. On January 7th 2010,
the Belgian Administration of Customs and Excise (regional office of Mons), delivered Soudokay
s.a., based in Seneffe (Belgium) the AEO-F certification (Authorized Economic Operator), certifying secure and reliable international companies.
AEO-F certification, and hence, the customs office’s lower risk classification, mean our customers now benefit from accelerated and more reliable supply processes beyond the borders of the
EU. AEO-F (full) status includes the status AEO-C (customs), which entails the simplification of
customs regulations, as well as the security conditions of the AEO-S (security).

We face the challenges !
… in steelworks – welding on of continuous casting rollers where particularly high demands
are placed on temperature and wear resistance with our specially conceived and proven fluxcored wires.
… in the cement industry – high mineral wear/abrasion combined with a heavy impact load.
Our stick electrodes were developed especially for use on vertical mills, crushers & hammers.
… in the mining industry – the most diverse minerals present big challenges. Here in particular
it is important to be present on-site by a network of technical dealers and field service employees in order to select the right products together with the customer.
… in the railway industry – our products have the necessary approvals and thus meet the
highest safety requirements in addition to guaranteeing constant high quality.
… in the construction of pumps, valves & fittings – we have the largest team of international
welding engineers in Europe who, thanks to their many years of experience are very familiar
with different materials such as cobalt or nickel-based alloys. In particular in consideration of
the environmental aspect is it of the utmost importance that valves, for example for subsea
applications, work defect-free.

direction of welding
In this technique, an electric arc is struck between a covered electrode and the workpiece;
the electrode acts both as the carrier of electric current and as the welding consumable that
will be melted. The electrode is melted in the high temperature of the arc, and transfers
to the weld pool in the form of drops. As this happens, gases that stabilise the arc and
shield the weld pool from oxidation, and slag that floats on the weld pool as protective
layer, are formed. This fulfils a number of functions: it protects both against the influence
of the surrounding atmosphere (primarily oxidation), binds contamination, and reduces
stresses by slowing the rate at which the weld pool cools down. A wide range of different
electrodes for shielded metal-arc welding are available. Their alloying elements allow the
strength and toughness of the weld seam to be accurately controlled. It is mainly used in
steel construction and pipeline construction, as well as for work in the open air and on
assembly jobs, since the necessary equipment is compact and can easily be transported.

UTP 614 Kb is a double coated stick electrode with a universally suited application field. It is
used in industry, trade, as well as in production and repair welds for diverse base materials.
Due to a special coating formula UTP 614 Kb shows a smooth and finely rippled weld seam,
a stable arc, easy slag removal, and a very slight increase of the weld, as well as a notchfree seam. The weld metal is little affected by steel impurities. Due to the double coating the
stick electrode is excellently suited for root- and out-of-position welding. Recovery 120%,

UTP 65 D has been developed to satisfy the highest requirements for joining and surfacing.
It is extremely crack-resistant when joining steels of difficult weldability, such as e.g. hard
manganese steels, tool steels, spring steels, high speed steels as well as dissimilar metal
joints. Due to the good corrosion and abrasion resistance and high tensile strength
UTP 65 D finds its application particularly in repair and maintenance of machine and drive
components, such as gears, cams, shafts, hot cuts, hot trim plates and dies. Also ideally
suited as an elastic cushioning layer for very hard surfacings.
UTP 65 D has outstanding welding properties. Stable arc, spatterfree. The finely rippled
seam has a homogeneous structure, very good slag removal, self-lifting on parts. Good
weldability in awkward positions. Stainless, creep resistant and workhardening.

32
UTP 2205 is a Cr-Ni-Mo alloyed duplex electrode for welding duplex steels such as 2205.
For light to moderate thickness material, welding should be carried out as for ordinary
austenitic stainless steel. However, the somewhat lower penetration and fluidity of the weld
should be considered. Very high quench rates and excessive times at red heat or above
should be avoided to prevent excessive ferrite or formation of intermetallic phases.
Interpass temp.:
Max. 150 °C.
Heat input:
0,5 – 2,5 kJ/mm.
Heat treatment:
Generally none
(in special cases quench annealing at 1100 – 1150 °C).
Structure:
Austenite with approx. 30 % ferrite.
Scaling temperature: Approx. 850 °C (air).
Corrosion resistance: Very good resistance to pitting and stress corrosion cracking in
chloride containing environments.

direction of welding
If a welding consumable is needed, it is supplied as a cold wire, and is melted in the arc in
front of the molten pool. The electrode, the arc and the molten pool are protected from the
effects of the atmosphere by an inert shielding gas – argon is usually used, or, more rarely,
the relatively expensive helium or a mixture of gases. The welding equipment consists of
a source of electrical current (DC or AC) and a welding torch connected through a hose
assembly. This assembly contains the cable for the welding current, the supply of shielding gas, the control line and, in larger equipment, a feed and return line for cooling water.
The decoupling of the supply of electricity from the welding consumables, which is typical
for TIG welding, allows highly individual adjustment of the parameters, so leading to very
clean, high-quality welded joints for root passes and position welding. There is hardly any
splatter and only a little welding fume, in addition to which lack of fusion, undercuts and
pores are easily avoided. TIG welding is therefore used wherever weld seams of particularly high quality are needed, such as in the construction of pipelines and apparatus, power
station building, aerospace engineering, and in the chemical and food industries. The TIG
technique can be applied manually or mechanically (whether semi or fully automatic), and
can be used to process any metal that is suitable for welding.

It can be used for joining ferritic steel to austenitic steel as well as for surfacing on steel. It
is also possible to weld 9 % nickel steels using this wire due to its high yield strength.
Its wide range of uses is of particular signifiance in aviation, in chemical industry and in
applications involving seawater.
The special features of the weld metal of UTP A 6222 Mo include a good creep rupture
strength, corrosion resistance, resistance to stress and hot cracking. It is highly resistant
and tough even at working temperatures up to 1100 °C. It has an extremely good fatigue
resistance due to the alloying elements Mo and Nb in the NiCr-matrix. The weld metal is
highly resistant to oxidation and is almost immune to stress corrosion cracking. It resists
intergranular penetration without having been heat-treated.

on such materials with a high Mn content as well as on steel and cast steel by using a
nodular iron rod. Because of the excellent resistance to seawater and general corrosion
resistance, the alloy is excellently suited in the shipbuilding industry (propellers, pumps and
armatures) and in the chemical industry (valves, slides, pumps) and is mainly for applications subjected to chemical attacks combined with erosion. Because of the good friction
coefficient it is suited for surfacing on waves, gliding surfaces, bearing and matrix of all
sorts.
UTP A 34 N is very good weldable in the TIG process. The weld deposit has excellent
mechanical properties and is tough and crack resistant. Very good chip removal machining,

base metal
The weld metal demonstrates good properties, and the method features high productivity,
whether applied manually or automatically.
The arc burns between the welding wire and the workpiece in gas shielded metal arc welding. The solid wire is automatically fed through the centre of the welding torch. The shielding gas is also passed through the welding torch, and encloses the weld pool during the
welding process. The weld seam is therefore shielded from the surroundings. The gases
used in MAG welding are active. Carbon dioxide, or a gas mixture, is used. In practice,
MAG welding under a mixture of gases has prevailed, as it has a lower tendency to spatter
and a higher deposition rate than welding using 100 % carbon dioxide.
In MIG welding, inert gases such as argon, helium, and their mixtures are used. These
shielding gases do not react with either the base materials or the welding consumables.
The MSG method can be used with a wide range of materials, welding position and degrees of mechanisation. It permits welding with a manually held torch as well as fully
automated robot methods. The deposition rate is very high, and productivity is high too.

UTP A 34 N is applied in MIG joining and surfacing on complex aluminium bronzes mainly
on such materials with a high Mn content as well as on steel and cast steel by using a
nodular iron rod. Because of the excellent resistance to seawater and general corrosion
resistance, the alloy is excellently suited in the shipbuilding industry (propellers, pumps
and armatures) and in the chemical industry (valves, slides, pumps) and is mainly for
applications subjected to chemical attacks combined with erosion. Because of the good
friction coefficient it is suited for surfacing on waves, gliding surfaces, bearing and matrix
of all sorts.
UTP A 34 N is very good weldable in the MIG pulsing method. The weld deposit has
excellent mechanical properties and is tough and crack resistant. Very good chip removal
machining, corrosion resistant and non magnetic.

base metal
FCAW is commonly used for welding thicker sections (> 5 mm). The high deposition rate
also makes it suitable for overlay welding of mild and low-alloy steel components. FCA
welding is closely related to Gas Metal-Arc Welding (GMAW) The flux filled wire is automatically fed through the centre of the gun using the same equipment as when GMAwelding. The shielding gas is supplied through the gun and protects the weld pool from
oxidation during welding. The flux inside the wire will protect the weld from the atmosphere since it forms a slag which covers the weld.
We recommend a shielding gas of either 75% Ar + 25% C02 or pure C02. The difference
between these concerns mainly the weldability, Ar + C02 being the best in horizontal welding and C02 in vertical welding. The FCAW process can easily be made automatic or semiautomatic. The method is very economical due to its high weld deposit rate.
Just like any other gas-shielded process FCA welding is sensitive to draughts. Arrangements to avoid draughts should therefore be made when site welding.

Characteristics and field of use
UTP AF 68 LC PW is a strip alloyed flux cored wire with a rutile slag characteristic for position welding of austenitic CrNi steels. The support provided by the fast-hardening slag allows
out-of-position welding with high current magnitudes and high welding speeds. The fine
droplet, low-spatter, very powerfully welding spray arc, the reliable fusion penetration, the
self-releasing slag and the effectively wetting seam formation result in a high weld quality
at the same time as short welding times. Additional advantages to its application result
from the ease of handling, the low heat input due to the high welding speed, and the small
amounts of cleaning and pickling required. UTP AF 68 LC PW is preferred for flat and horizontal welding positions (PA, PB). The weld metal is cryogenic down to – 196 °C and resists
intergranular corrosion up to + 350 °C.

Characteristics and field of use
UTP AF 6808 Mo is a strip alloyed duplex steel rutile flux cored wire for gas shielded arc
welding primarily in flat and horizontal welding positions. It can provide an economical and
qualitatively advantageous alternative to MAG welding of duplex steels.
The easy handling and high deposition rate of UTP AF 6808 Mo result in high productivity
with excellent welding performance, self-releasing slag, very low spatter formation and
seam oxidisation, finely rippled weld pattern with good wetting behaviour and even, reliable
fusion penetration. In addition to the significant savings in time and costs of processing
techniques, including the lower requirement for cleaning and pickling, we guarantee a high
level of quality and highly reliable avoidance of welding defects.
The structure of the weld metal consists of austenite and ferrite (FN 30 - 50). The pitting
resistance equivalent is PREN ≥ 35 (%Cr+3,3%Mo+16%N). In the welded and pickled condition, the weld metal is resistant, according to ASTM A262-93a, Pr.E, Pr.C, Pr.B and ASTM
G48/Method A up to 22 °C, and according to ASTM G48/Method A (24 h) in the solution
treated and pickled condition up to 30 °C. The welding consumable can be used in a temperature range from – 40 °C up to + 250 °C.
Base materials
Same-type duplex steels and similar-alloy, ferritic-austenitic materials of increased strength,
as well as for dissimilar joints between duplex steels and unalloyed or low-alloy, creep
resistant and austenitic steels.

Characteristics and field of use
UTP AF 6808 Mo PW is a strip alloyed, duplex steel rutile flux cored wire for position welding of duplex steels in the chemical apparatus, plant and container construction, for chemical tankers and in the offshore industry. The support provided by the fast-hardening slag
allows out-of-position welding with high current magnitudes and high welding speeds. The
advantage of the slag is its supporting effect on the weld pool. This permits, for example,
welding with the stringer bead technique at a correspondingly high welding speed even in
difficult pipe welding positions (5G, 6G). The fine droplet, low-spatter, very powerfully welding spray arc, the reliable fusion penetration, the self-releasing slag and the effectively wetting seam formation result in a high weld quality at the same time as short welding times.
Additional advantages to its application result from the ease of handling, the low heat input
due to the high welding speed, and the small amounts of cleaning and pickling required.
The structure of the weld metal consists of austenite and ferrite (FN 30 - 50). The pitting
resistance equivalent is PREN ≥ 35 (%Cr+3,3%Mo+16%N). Testing the weld metal in accordance with ASTM G48 Method A resulted in a CPT (critical pitting temperature) of 25 °C.
Also suited to joining diffe rent materials and to weld cladding. Usable between – 46 °C and
+ 250 °C.

SAW = Submerged Arc Welding
Submerged arc welding is an arc welding
process in which the arc burns between an
electrode (wire or strip) and the workpiece.
The special feature of this method is that
the arc burns out of sight in a cavity, filled
with gases and vapours, under a layer of
coarse-grained, mineral welding flux.
SAW – solid wires and fluxes
Description of the SAW process
wire electrode
flux
weld metal
slag
349
base metal
The welding flux melts in the arc, forming a liquid slag that floats on the molten pool, so
protecting it from the effects of the atmosphere (like the shielding gas in gas shielded arc
welding). The welding electrode, whether wire or strip, is supplied by an automatic feed
system, while the welding flux is supplied from a reservoir or through a compressed air
feed system. The welding current flows via a contact tube to the electrode immediately
above the welding area. This has several advantages, including high current carrying capacity, high deposition rate, and a wide range of possible variations of the welding parameters. The flux coating, moreover, results in high thermal efficiency, and submerged
arc welding is therefore known as a high-efficiency process. Turning to detail, there is a
distinction in submerged arc welding between single-wire welding, double-wire welding,
tandem welding and strip welding.
The composition of the weld metal can be influenced through the right selection of the
electrode and flux combination, since chemical reactions between the melt and the slag
can control the burn-off and pick-up of alloying elements. The method generates very few
emissions, and creates spatter-free seams of high quality.
It is a fully automated welding procedure carried out, for instance, using welding gantries,
booms, motorised axis systems or carriages, most often for welding long seams in an
industrial context. The method is often employed in shipbuilding, container manufacture,
bridge building and steel construction. The method can be applied for joint welding and
for build-up welding, for instance for wear or corrosion protection layers.

It can be used for joining ferritic steel to austenitic steel as well as for surfacing on steel. It
is also possible to weld 9 % nickel steels using this wire due to its high yield strength.
Its wide range of uses is of particular signifiance in aviation, in chemical industry and in
applications involving seawater.
The special features of the weld metal of UTP A 6222 Mo include a good creep rupture
strength, corrosion resistance, resistance to stress and hot cracking. It is highly resistant
and tough even at working temperatures up to 1100° C. It has an extremely good fatigue
resistance due to the alloying elements Mo and Nb in the NiCr-matrix. The weld metal is
highly resistant to oxidation and is almost immune to stress corrosion cracking. It resists
intergranular penetration without having been heat-treated.

Submerged arc (SAW) strip cladding can easily be compared to submerged arc welding
with wire. You “only” have to replace the wire by a strip. The strip is fed through two driving
rolls. The current is transfered to the strip by two contact shoes, which have approximately
the same width of the strip and are especially designed for optimal current transfer to
the strip. The flux is fed from two sides by two flux hoppers. The bottom of the strip is
therefore totally submerged by flux. The energy needed to melt the strip is provided by an
electric arc. The flux is also melted and a liquid slag forms on the top of the liquid metal. As
the process progresses, the slag solidifies and detaches automatically.
n High deposition rate
n High quality weld metal
n Easy slag removal

The electroslag welding process (ESW) slightly differs from the SAW strip cladding process in the fact that the flux is fed only from one side and that there is no electric arc. The
liquid slag is electroconductive and conducts the energy required to melt the strip and flux
by Joule-effect. When the strip arrives in the welding pool, it melts. As the slag solidifies,
it forms a protective layer on the hot metal and then detaches automatically.
n Lower penetration
n Lower dilution (down to 7 %)
n High current density resulting to higher deposition rate (up to 50 kg/h)
n Open weld pool
n Special high speed fluxes (up to 45 cm/min)
n High deposition rate (up to 1,2 m2/h)
n Perfect overlap and very flat bead surface with magnetic steering
n Low flux consumption

In powder flame spraying, the spray material, in powder form, is melted with an oxy-fuel
gas flame, accelerated towards a component by the combustion gases and sprayed on
to the surface of the component. Metallic, oxide ceramic, carbide and plastic powders
can be processed using spray guns specifically designed for those materials. Spray guns
that frequently take the form of manual torches, preferably using acetylene as a fuel gas
because of its high flame temperature, are chosen for metallic alloys based on nickel,
iron or cobalt. The powder particles, which are partially melted by the flame, deform on
impact with the surface of the component and are deposited there to form a spray coating
with a lamellar structure. The main areas of application for thermal coatings are corrosion
protection and wear protection.

Arc Spraying is the highest productivity thermal spraying process. A DC electric arc is
struck between two continuous consumable wire electrodes that form the spray material.
Compressed gas [usually air] atomizes the molten spray material into fine droplets and
propels them towards the substrate. The process is simple to operate and can be used
either manually or in an automated manner.

Plasma powder surfacing (PPS), also known as the plasma transferred arc (PTA) process,
is a thermal coating process. In contrast to the spraying processes, this method is a
welding process and so involves metallurgical bonding of the applied material to the base
material. However, if the parameters are set optimally, the degree to which it blends with
the base material can be reduced to a minimum. The PTA process is employed primarily
for surfacing of wear resistant and corrosion resistant coatings on to a base material.
The process is characterised by the use of two separately controllable electric arcs. One
of these is the (non-transferred) pilot arc; this arc is formed between the non-melting
(tungsten) electrode and the plasma nozzle. It accelerates the plasma gas and enables
ignition of the (transferred) main arc. This arc burns with a high energy density between
the electrode and the workpiece. With the aid of the electric arc, both the base material and
the metal powder that serves as the welding consumable are fused together, which then
gives rise to the deposited protective coating. Ar, H2, He, or mixtures of gas are employed
as a processing gas. This serves, firstly, as a plasma gas and, secondly, as a shielding gas
and as a carrier gas for the powder.
In smaller grain sizes (typical 45 – 125 μm) also suitable for Laser Welding.

Classifications
covered electrode
Characteristics and field of use
Special products
The strongly coated chamfering stick electrode UTP 82 AS can be used on all steel grades
with ferritic and austenitic structure, as well as cast iron, cast steel and all non-ferrous
metals. It enables workpieces to be grooved out in a very simple way. UTP 82 AS is also
suitable for removing corroded metal layers and for fusion-cutting metallic materials.
470
UTP 82 AS strikes easily and generates a high gas pressure, enabling a clean and smooth
cut to be achieved.
Welding instruction
When grooving it is advisable to tilt the plate in the direction of working, so that the molten
parent metal can run off better. The stick electrode should be inclined to the parent metal
as horizontally as possible (approx. 15°) and kept constantly in contact with it. The working
speed is increased by slight pushing movements in the direction of working. Parent metal
left on the edge of the groove is easily removed with the slag hammer. Machining the
groove down to the bare metal may be advisable, depending on the circumstances.

Welding instruction
Strike the arc by holding the electrode perpendicular to the workpiece, thereafter the electrode should be pointed in the appropriate direction and pushed forward. Keep the electrode
in contact with the workpiece and move it like a handsaw. If a deeper cut is required, repeat
the procedure until the desired depth is reached.
To pierce holes, simply hold the electrode vertical, strike the arc and push through the base
metal, removing the electrode immediately once the hole is made. The size of the hole may
be increased by moving the electrode in a circular motion.

Guidelines for the storage and transport of
cored welding wires for general applications
Appendix
1. General conditions
1.1 These guidelines are valid for general application for storage and transport of cored
welding wire. This does not however release the user from his duty and responsibility
in convincing himself of the faultless condition of the welding consumables in question.
490
2. Storage and Transport
2.1 Whenever welding consumables are transported, care must be taken that the material
itself or the packaging is not damaged. The stacked height of cartons and packages
should not exceed 6 units.
Precautions should be taken that older deliveries are used before newer ones (first in,
first out).
Precautions should be taken to avoid storage in damp areas while in original packaging
condition. To protect welding consumables against moisture pick up during long term
storage, store preferably in a room with max. 60 % relative atmospheric humidity and
a temperature of 18 – 23 °C. Temperature fluctuations should be avoided in order to
prevent condensation.
Storage in direct contact with the floor or walls should be avoided.
2.2 Seamed and seamless cored wires in undamaged packages can be stored under mentioned conditions for a term of two years without reapplied usability testing. Start of
storage term is the date when the purchaser’s reception control certifies the correct
status of the delivery directly after its incoming.
2.3 Improper storage and handling of cored wire can cause visible damage to the welding
consumables. They may show defects such as kinks, bends and rust.
3. Redrying of flux cored wires
Even though the storage conditions as in section 2 are maintained it is probably necessary to redry seamed cored wires before they are welded because of safety cases.
Therefore the cored wires have to be unpacked and placed in the drying oven. A redrying temperature of 150 °C is recommended and should be maintained for a duration of
3 hours. In general the redrying procedure is limited to 24 hours.
Seamless cored wires do not require a redrying process.
Attention: Cored wires delivered on plastic spools can not be redried!

Guidelines for the storage and transport of
solid welding wire and rods for general applications
1. General conditions
1.1 These guidelines are valid for general application for the storage and transport of solid
welding wires and rods for arc welding. This does not however release the user from
his duty and responsibility in convincing himself of the faultless condition of the welding consumables in question.
Appendix
2. Storage and Transport
2.1 Whenever welding consumables are transported, care must be taken that the material
itself or the packaging is not damaged. The stacked height of the cartons and packages
or sacks should not exceed 6 units.
Precautions shall be taken that older deliveries are used before newer ones (first in,
first out).
Precautions should be taken to avoid storage in damp areas while in original packaging condition. To protect welding consumables against moisture pick up during long
term storage, store preferably in a room with a maximum of 60 % relative atmospheric
humidity and a temperature of 18 – 23 °C. Temperature fluctuations shall be avoided in
order to prevent condensation.
491
Storage in direct contact with the floor or walls shall be avoided.
2.2 All welding consumables that have been removed from their original packaging and
not used for an extended period of time shall be stored in a clean and dry room, which
is free of dust and sufficiently ventilated. Welding consumables showing evidence of
deterioration following extended periods of exposure shall not be used.
2.3 Improper storage and handling of solid welding wire and rods can cause visible damage to the welding consumables. They may show defects such as kinks, bends and
rust.
3. Guarantee
Provided that the guarantee conditions have not been otherwise agreed upon in individual contracts, a guarantee period of 12 months is guaranteed. Substitution claims will
be regulated according to our general conditions of delivery and payment, in the event
that claims, regardless of type, should be derived from the above recommendations.

Guidelines for the storage and rebaking of welding consumables
for nuclear power plants and general applications
1. General conditions
1.1 These guidelines are valid for the storage and rebaking of all kinds of welding consumables which are determined for the application in the nuclear sector. This does not
however release the user from his duty and responsibility in convincing himself of the
faultless condition of the welding consumables in question.
Appendix
1.2 We also recommend the use of these guidelines for all consumables determined for
general application.
492
2. Storage
2.1 Whenever welding consumables are transported, extreme care must be taken that the
material itself or the packaging is not damaged. The stacked height of the cartons and
packages or sacks should not exceed 6 units.
Precautions should be taken that older production lots are used before newer ones.
2.2 All filler metals have to be stored in a clean and dry room which is free of dust and
sufficiently ventilated. To protect the electrodes/fluxes against moisture pick up during
storage, they should be stored preferably in a room with max. 60 % relative atmospheric humidity and a temperature of 18 – 23 °C. Temperature fluctuations have to be
avoided in order to prevent condensation.
Improper storage and handling of bare solid welding wire and rods can cause visible
damage to the filler metals. They may show defects such as links, bends and rust.
The storage in direct contact with the floor or walls should be avoided.
2.3 Under the above mentioned conditions and in undamaged packaging, coated electrodes and fluxes can be stored for a maximum of 2 years, without further testing
(KTA 1408.3) before usage. The storage period begins at the point when the customer
acknowledges the proper conditions of the merchandise, immediately on receipt of the
delivery.
3. Rebaking of coated electrodes and flux
3.1 Even when the storage conditions mentioned in paragraph 2 have been observed, it is
advisable, as a safeguard, to rebake the electrodes/fluxes before welding. Before starting the rebaking process, the electrodes should be removed from the packages with
the appropriate care and laid in the baking oven. Under no circumstances the stacked
height of the electrodes/fluxes in the oven should exceed 40 – 50 mm.
For rebaking, the filler metals should be hold at the rebaking temperature of at least 2
hours.
The electrodes can be rebaked several times, although the total rebaking time must not
exceed 10 hours.

5. Cellulose-electrodes
Cellulosic coated electrodes are produced with a well defined moisture content in the
coating. These electrodes are packed in tin cans. Cellulosic electrodes may never be
redried.
Appendix
6. Vacuum-package “Extra-Dry”
On special customer’s desire electrodes can be packed in a vacuum package. These
electrodes can be used without rebaking in a period up to 9 hours after opening the
undamaged package. Thereby you will achieve H2-contents less than 5 ml / 100 g
weld deposit.
Electrodes which are not used out of the vacuum package (within 9 hours) can be
regenerated by rebaking at 300 – 350 °C for 2 h.
494
7. Return of the electrodes from the working area
After bringing back the coated electrodes/fluxes from the working area, rebaking as
mentioned in paragraph 3 is always necessary.
The return of open packages to stock is not permissible.
8. Guarantee
Provided that the guarantee conditions have not been otherwise agreed upon in
individual contracts, a guarantee period of 12 months is guaranteed. Substitution
claims will be regulated according to our general conditions of delivery and payment, in the event that claims, regardless of type, should be derived from the above
recommendations.

Material test certificates according to EN 10 204
Increasingly, certificates attesting the characteristics and property values of the welding
filler metals are required by customers or inspection authorities within the framework of
the acceptance testing of weldments.
A few explanatory notes are given below with the request that they be kept in mind when
making inquiries or ordering.
Appendix
The EN standard 10 204 is taken as a basis to determine the schedule of such certificates
in the case of inquiries and orders. EN 10 204 defines who is responsible for testing and
authorized to sign, and whether the certificates must contain details concerning general
typical values or specific test results relating to the particular delivery in question.
We would like to emphasize strongly that the EN standard 10 204 does not contain the
following details and that these must be specified by the customer when ordering:
Scope of testing:
e.g. type and number of tests, individual elements in case of
chemical analyses
Consumables:
e.g. type of shielding gas, etc.
Test paramenters:
e.g. postweld heat treatment of the test piece, test temperature
Requirements:
e.g. minimum values for yield strength, tensile strength,
elongation, impact values, chemical composition tolerances
Inspection society:
e.g. TÜV, Germanischer Lloyd, DB

Caution: Because of their approximate nature, conversion tables must be regarded as only an estimate of
comparative values. It is recommended that hardness conversions be applied primarily to values such as
specification limits, which are established by agreement or mandate, and that the conversion of test data be
avoided whenever possible.

Metallography structures
1. Austenitic
Appendix
Field of use & properties comments
498
An alloy that after solidification and cooling down to room temperature according to such
microstructure is generally qualified as an austenitic one. Alloying elements stabilizing the
austenite structure are most of the time Carbon, Manganese and Nickel but Chromium and
Niobium might be used in combination in order to modify work hardenability and/or abrasion resistance. Austenitic alloys appreciated for building-up tasks, buffering prior overlaying with carbide containing alloys. Austenitic alloys with up to 0,7 % C and 20 – 30 (Mn + Cr)
% with or without Ni, providing very stable austenite are appreciated for overlay on carbon
and low alloyed steels no matter the dilution could be as well for joints on “hard to weld”
steels or dissimilar joints between carbon or low alloy steels and 14 % Mn Hadfield steels.
Carbon level has a relative low influence on the final hardness at room temperature. High
Manganese steels should not be exposed over long time intervals to temperatures exceeding
350 °C in order to avoid any embrittlement by carbide precipitation.
Main characteristics
Usual Austenitic & Martensitic single microstructures used in overlay welding.
n Work hardenable
n Fairly resistant to rusting
n Not magnetic in as cast state
n Not hardenable by heat treatment
n Strongly resistant to impacts
n Cannot be flame cut
n Not prone to crack propagation
n Moderately resistant to abrasion most over in the work hardened state
Metallography structures
2. Martensitic
Field of use & properties comments
3 subfamilies of martensitic alloys are existing: unalloyed (mainly alloyed with C & Cr), medium alloyed (alloyed with C, Cr < 11 %, Mo, W, V, Nb) & stainless grades (alloyed with min.
12 % Cr). The martensite is a microstructure out of equilibrium, obtained by rapid cooling,
the faster the cooling rate, the harder the microstructure. Low carbon, unalloyed martensitic
alloys are primarily used for building-up to original dimensions or for buffering prior to
hardfacing with harder materials. Overlay welding with martensitic alloys (as substrate or
consumable) generally require preheating (≥ 150 – 350 °C depending on chemistry and
thickness concerned) in order to avoid cold cracking due inappropriate cooling rate. Medium
alloyed martensitics thanks to their good tempering resistance may be used to repair welding
on cold & hot working tool steels up to 500 – 550 °C.

Chapter_11_Appendix.indd 498
16.08.13 16:06
Stainless martensitic alloys are fairly resisting to thermal shock, to wet corrosion and show a
good behaviour face to adhesion and hot oxidation that makes them appreciated for overlays
on caster and steel mill hot rollers and for Sulphur bearing fumes exhaust systems. These
alloys don’t suit for joining purposes nor used for overlaying austenitic grades.
Main characteristics (2. Martensitic)
Usual Austenitic & Martensitic single microstructures used in overlay welding
n Generally good resistance against impacts up to 0,5 % C
n Quite high resistance against compressive stresses
n High response to heat treating
n Particular good behaviour to adhesion wear (metal to metal sliding wear)
Appendix
n Prone to crack propagation
n Low resistant to rusting with exception for martensitic stainless grades
n Resistant to hot oxidation up to 800 °C and to hot corrosion for stainless grades

3. Complex carbide microstructure with austenitic or martensitic iron matrix
Field of use & properties comments
Alloys of this family perform very well when abrasion is concerned thanks to their variable
proportions of widely dispersed carbides. Therefore most of these alloys contain as main alloying elements both carbon and chromium. Low carbon (1,5 – 3 %) favours small carbides
quantities related to the matrix so they exhibit good abrasion resistance combined with a
good toughness properties m aking them capable to make a good compromise when both
shocks and abrasion are present.
Increased level of carbon (up to 6 – 7 %), allow to boost the carbide number and sizes while
the matrix progressively loses its toughness. As consequence of this, relief check cracks
appear more frequently and are closer from each other’s. With a few exceptions requiring
specific procedures, it is generally preferred to use these alloys on substrates buffered with
austenitic layers avoiding check cracks to move to the base material. The risk of spalling
associated with check cracks and high hardness imposes to minimise the number of layers
to 3 or 4. Combination of large and small carbides sizes allow to extend the abrasion wear
resistance to fine abrasive particles.
Main characteristics
n Highly resistant to abrasion under low & high compressive stresses.
n Moderate to low resistance to impacts
n Only machinable by grinding
n Fairly resistant to corrosion
n May develop relief check cracks
n Good resistance to heat
n Cannot be flame cut
