Fundamentals of the MIG/MAG welding process
Principle of the MIG/MAG welding
process
Tt1e wire feed rollers feed the wire electrode from the
reel to the contact tip. An arc is created between the wire
electrode and the workpiece. The wire electrode thus
becomes the arc carrier. The arc melts the workpiece
point by point and forms the weld pool. The wire electrode melts and drips into the weld pool, thus forming the
filler metal. The inert gas flows from the gas nozzle and
protects the arc and weld pool from atmospheric gases.
(~l1 '~)
L Wire feed rollers
Wire electrode - - - -'
--~~~~-------~!-~.-~Y.P.~~- - ····------------ .. . ' -.. ------Short arc
This type of arc is particularly suited to the welding of
thin sheets, in root layers and for welding in restricted
locations because of its relatively "cold" weld flow. In this
case, the welding takes place with a very short arc, at
low arc voltage and at low current intensity. Due to the
surface tension of the melt pool, the drop is drawn into
the molten metal and the arc is reignited. This recurring
cycle creates a continuous alternation between the short
circuit and the arcing period.
The transition from short to spray arc is dependent upon the gas mixture and the wire
diameter.
Transition arc
A transition arc is used for medium plate thickness and
Gas noz------"
for vertical down welds. The material transfer tales place
both in short circuit and in free flow. This produces a reduced short circuit index and a slightly "hotter" molten
pool than in the short arc. Transition arc welding has a
higher melting rate than short arc, and is therefore more
economical.

Long arc
Fig. 17:
MIG/MA G welding processes
There are two types of metal inert gas welding that are
differentiated by the type of inert gas that is used: Metal
inert gas welding (MIG), inert gas) and metal active gas
welding (MAG, active inert gas).
Long arcs are typically used for welding under carbon
dioxide and under high C02 containing gas mixtures in
the upper performance range. Long arc welding is not
really suitable for welding in tight spaces. Larger drops
fall into the molten pool largely by gravity. This sometimes involves short circuits which, al the point of the
short circuit, can produce spatter when the arc Ignites
again, because of the upslope.

Tab. 2:
Dlle to the thinness of the melt pool, spray arc welding
is not suitable for welding in tight spaces. ft is used for
welding in the higher power range using inert gases or
gas mixtures with high argon content. The spray arc has
a very fine drop, short-circuit free material transfer.
MIG/MAG welding processes
The welding processes are further differentiated by arc
type. This means that tt1ere are differences in the form
of the arc, short circuit tendency and material transfer
mode.
Selection of the type of arc is only possible to a limited
extent. e.g. when short arc welding. Short arc welding is
possible using all metal inert gas welding processes by
the selection of the suitable current intensity and the associated arc voltage, although the short circuit frequency
and drop size are very different, according to the inert
gas being used .

Good weld qualities are only achieved if the voltage and
current are well balanced.
When using C02, an arc voltage which is around 3 V larger Is required than when using argon-rich gas mixtures.

Working ranges for MAG welding
Holding and guiding the torch
CD
With metal shielding gas welding, you can
work in all positions: Level , horizontally.
vertically from top lo bottom, vertically from
bottom to top, overhead and in lateral position.
For level and horizontal and level welds, hold the torch
verticailly (neutral torch position) or pushing at up to 30°.
On thicker layers, you can also drag the torch slightly.
The neutral torch position produces the best penetration
depth and inert gas coverage. Take care not to tilt the
torch too much. otherwise air could be drawn into the
inert gas shield by the injection effect.
If you are welding vertically and overhead then you
should push the torch slightly. Down welds are usedl
mainly for welding thin plates. In this case, hold the torch
in as neutral or slightly dragging position. This technique
requires specially trained and experienced welders,
since there are dangers from incomplete fusion due to
the forward melt pool. This danger increases with thicker
materials, or if the melt pool is very thin because the voltage is too high.
Avoid larger oscillating movements in order to prevent
the melt pool from building up in front of the arc. This can
lead to incomplete fusion due to the forward melt pool.
Except in the vertical up position, you should oscillate
laterally only as far necessary to cover both edges of the
seam. If the seam is sufficiently wide, weld two beads
alongside each other.
If you are welding in the vertical up position, your oscillations should be in the shape of an open triangle.
Arc length
The longer the arc, the shallower the penetration depth
is, the wider and natter the weld bead and the greater
the tendency to spatter. The weld metal is transferred in
slightly larger drops compared with a shorter arc. Use a
longer arc when fillet welding, in order to produce a flat
or concave weld bead.
A shorter arc increases the penetration depth (at the
same current intensity), the weld bead is narrower and
the tendency lo spatter is reduced. The weld metal is
transferred in finer drops until the short arc is reached.
Long arc

Arr; length
Electrode wire length
In general, the distance between the torch and the workpiece is 10-12 times the wire diameter. You can also
change the torch distance to affect the length of the free
end of the electrode.
A longer free end of the electrode reduces the current
intensity and the penetration depth.
A shorter free end of the electrode increases the current
intensity while maintaining the same wire reed rate.
