CHAPTER IX Body Dimension
I. Basic Instructions on BIW Maintenance
Vehicle body maintenance should be carried out by professionals according to the requirements of the
manufacturer, and only in this way will the promises of “rust free” and “paint defect free” be effective.
1.
2.
3.
Only adopt the materials specified by the manufacturer;
When welding the outside metal of the vehicle body, make sure protective coating is applied to
the inner side;
When spot-welding, make sure zinc coating is used;
4.
Before air-tight sealing the welded parts, apply a layer of filling coating to the inner side and
outer side;
5.
Before protecting the chassis with paint, apply protective coating to protect the chassis from
rock bumping;
6.
When the coating is sprayed, all opening parts at this position should be secured with
fasteners;
In some cases, the vehicle must be placed on a hoister platform, for removal of spare parts may affect
the distribution of various parts in the vehicle body.
Before spot-welding, make sure the battery connector is unplugged, and check if the ventilation is good
enough before welding.
In maintaining the vehicle body in a certain area, take care to protect other vehicles in this area.
Be particularly careful when spraying sand or welding near the oil tank or fuel system, and disassemble
them if the safety can not be assured.
When maintaining or spray-painting the vehicle body, take all possible measures of preventing
accidents.
When welding galvanized steel sheets, the spot-welding current should be raised by 30%, and the
electrodes should be pointed, and the clamping force of the electrodes should be increased; and when
doing gas shielded welding, the welding current should be further intensified.
Do not weld the air-conditioning parts or try to weld the parts on the vehicle whose temperature are
easily raised. When spray-painting the vehicle frame, the temperature either in the drying oven or the
pre-heating oven should not go beyond 80˚C.
Take the following measures during welding operation to prevent shaking the electronically welded
equipment:
Connect the grounding of the electronic welding equipment directly to the welded parts. And check to
make sure no other parts or insulative parts exists between the ground wiring connector and the spotwelded parts;
First disassemble the ECU, and prevent the electronic device or circuit from contacting the ground
wiring connector or welding wire.
Corrections:
The vehicle body and the chassis are manufactured off the production-line by low-temperature
tempering and cold die casting. Therefore, when the metal parts are damage in any accident, the same
processes must be used to restore them, and no heating is allowed. If they are damaged very seriously
and can not be restored, the damaged parts must be removed after the connecting surface is corrected.
The car bodies are made up of various members, pressing panels and other parts, of which the doors
are the most complexly processed parts of the vehicle body. They involve processes like part stamping
and welding, assembly of spare parts and assemblies, for which the dimensional fits and technical
requirements are quite strict, so the car doors are difficult to maintain and the quality requirements are
fairly high, and only the service personnel understand the structure of the car doors thoroughly and are
56
Chery S18D Service Manual
qualified for the maintaining operations.
1. Vehicle Door Structure
Generally speaking, the vehicle doors consist of outside plates, inside plates, window frames, glass
guide rails, hinges, locks and window accessories and so on. The inside door plates are equipped with
accessories including glass lifter, locks and so on. To secure the assembly, some parts of the inside
door plates need to be fortified. To increase safety level, the inner parts of the outside plates are usually
equipped with impact bars. The outside plates and inside plates are connected by flanging, adhesion,
seam welding and so on. Depending on different bearing capabilities, the outside plates should be light
and the inside plates should have higher rigidity and be able to stand stronger impact.
The BIW vehicle door assemblies have relatively fewer components, and usually consist of inside
plates, outside plates, glass guide rails, window frame reinforcing plates, lock mounting plates, hinges
reinforcing plates, impact bar assemblies and so on; The figure below is a typical structure drawing of a
vehicle door.

2. Door Panel Maintenance Process
Generally speaking, the basic maintenance methods for car doors and hoods are the same as those for
ordinary plate work, and the following procedures apply to both of them:
(1) Primary tests. The positions of the door panels as related to other assemblies of the vehicle body
as well as the dimensions of their tolerance clearances should be tested
57
Chery S18D Service Manual
(2) Clean the vehicle doors. Use fresh water or detergent to clean the dirt and greasy spots on the
door panels, and let them thoroughly dry for tests.
(3) Maintenance appraisal. Appraise the scope and degree of damage to the door panels by testing
and decide the maintenance methods.
(4) Clear the old paint. Before cleaning or maintenance, get rid of the old paint according to the actual
situation, especially when there exists obvious rust, cracks or dents; The paint can be got rid of in
manual, heating, mechanic or chemical method(s).

Scraper
Fig. 3
(5) Tests after the removal, including the measurements of the geometric dimensions between various
plate work pieces, tests of specific damage spots of various plate work pieces, recognition of
damage types, analyses of damage causes and choices of maintenance schemes.
3. Main Contents of Door Panel Maintenance
Generally speaking, the causes of door panel damages are related to the following 4 aspects: structure
design defects, manufacturing defects, chemical erosion, and physical damage. And the most common
damage causes can be classified as the following types:
1.
Abrasion: The surfaces of plate work pieces may contact each other and relative movements will
take place and cause surface friction, which will lead to abrasion. For example, the long time
friction between the hinge hole and the shaft of the vehicle door hinge will increase their tolerance
clearance and cause to vehicle doors to drop.
2.
Erosion: This is generally due to the oxidation caused by the mud deposit and dirt; or the rust
caused by lack of anti-erosion processing after welding; or erosion caused by chemicals. This type
of damage usually occurs between the plate work pieces, in overlapped parts of spot-welded
pieces, and at other similar places.
3.
Cracks or breaks: The metal plates may develop fatigue under repeated inner/outer stress where
the stress concentrates and the structure is the weakest, causing cracks and even breaks.
58
Chery S18D Service Manual
4.
Dents or wrinkles: Dents develop because the door panel is subjected to bumping or pressing,
leading to elastic or plastic deformations.
5.
Bends or twists: They are mainly caused by too much load the door panel receives in use or the
plastic deformation due to bumps.
4. Basic Methods for Door Panel Maintenance
The basic maintenance methods for the above door panel damage types include dent reconditioning,
flame correction, welding, repairing and mending, wrinkle spreading and so on.
4.1. Reconditioning of Dents
For convex-concave damages in the outside door panels, if they are indirectly caused by structural
pieces or reinforcers, the structural pieces should be corrected first, and then the outside panel breaks
or dents are to be corrected. If the backs of the metal panels are accessible, hand hammers and
underlay irons or spoon-shaped irons, tommy bars, flat punches and so on can be used for primary
repairs. For enclosed metal panels or parts that are difficult to access from the backs, other tools can
be used for repairing, such as slide hammers and pointed hammers.
Here are some common ways of dent reconditioning:
(1) Repair the dents with underlay irons and hand hammers: the commonest practice is to beat the
damaged metal panels with underlay irons and hand hammers. Both sides of the metal panel to be
repaired must be accessible to the hand-held underlay iron and there are two ways of using the
underlay iron as the supporting piece for the hand hammer:
①
Beat with a hammer from above the underlay rion. This approach is suitable for correcting
smaller and shallower dent or breaks.
When beating with a hammer from above the underlay rion, the hand-held underlay iron
should be placed against the back of the metal panels, and then beat the convex part. The
beating of hand hammer can make the metal panel contract and finally smooth the metal
panel.
59
Chery S18D Service Manual
②
Beat with a hand hammer from other parts than from directly above the underlay iron. The
underlay iron is placed against the lowest part of the dent, and then the higher parts near the
dent are beaten with a hand hammer.
Generally, when trying to repair the dent with a hand hammer and an underlay iron, the convex
side is beaten with the hand hammer and the concave side is pressed against the underlay
iron. First do brief correction by beating the damaged part with a wooden hammer, and then do
finer repairing with an iron hammer. For a larger area of dent, the underlay iron should be
placed against the place where the dent is shallower, and the hand hammer should beat the
higher parts. Besides, the wooden hammer and the iron one should be used alternatively
according to the actual situation.
(2) Repair the dent with a shaping spoon or tommy bar. Shaping spoons and tommy bars are
commonly used tools for door panel maintenance, and they are customized according the
characteristics of the vehicle body. They can reach the limited space between door panels to push
up the dent. This method is suitable for the narrow room between the door panels where it is
inaccessible for the underlay iron or the hammer, and the shaping spoon can act as a underlay iron
to distribute the impact of the hammer over a larger area.
(3) Restore the dent with a dent smoother. The dent smoother is applied to the inner side of the metal
panel and it is used for the dents that are hardly accessible to other tools and it is usually operated
in the following two ways:
Slide hammer

Handle
Fig. 8
Flat gasket
Handle
Fig. 9
Puncturing: Drill a small hole in the dent with a hand power drill, and then insert a pull-rod with threaded
head or hook-shaped head into the hole. Slide the slide hammer on the metal pull-rod and impact the
handle repeatedly so as to pull up the dent gradually. Make more than one holes when necessary, and
fill the hole(s) by soldering and polish the spot(s) when the dent(s) is/are smoothed.
Electrode welding: Weld a peg or a flat gasket onto the dent with a special spot-welder, and then use a
dent smoother to pull at the peg or flat gasket till the dent is smoothed. More than one peg or flat
gaskets can be welded when necessary so that the whole dented area can be dragged out. Finally,
break the peg or flat gasket, and polish the welded scar with a sand mill. This method can avoid drilling
the metal panels and prevent potential erosion, so it is widely used.
4.2. Restoration of Stretched Parts
When the metal panel is impacted, the dented area would be stretched. At times even proper
operations can not restore it, the heating-contracting method is sometimes used to achieve the desired
60
Chery S18D Service Manual
repairing effect.
(1) Heated position and flame intensity: The effect of flame correction depends on the heated position
and the flame intensity. Different heated spots bring about different effects, and the heated position
should be where the material is deformed the most and the metal panel is stretch the most, or the
furthest part outward that is bent and deformed. Different flame intensities also lead to different
correcting effects. The intenser the flame is, the faster the metal panel is heated and the more
concentrated the heat is, and then the stronger the contracting capability is. The low-carbon steel
panel, for example, should be heated till it gets cherry red (600℃ - 800℃).
(2) Heating ways normally adopted for flame correction in the vehicle body maintenance are:
①
Spot heating: The heated area is a round spot of a certain diameter, which is usually 15 30mm. One or more spots can be heated according to the actual deformity situation. When
more than one spot is heated, the spots are arranged in a plum pattern. And this way is often
used for contracting the convex area in the middle of the panel.
②
Triangle heating: The heated area resembles a triangle, and this way is often used for
correcting strip-shaped materials and deformed panel edges.

(3) Cooling-contracting way: When the flame is taken away, proper cooling ways should be chosen
according to the stretched degrees of the metal panels. Different cooling ways bring about different
contracting effects.
①
Natural cooling-contracting, or cooling in the air naturally, which is suitable for smaller areas of
deformities.
②
Water cooling, or covering the heated area with wet cotton cloth to make it cool suddenly. The
contraction of metal plate cooled in this way is larger than that of the naturally cooled one, but
it may make the steel panel fragile.
③
Natural cooling and hammering, usually operated with a hand hammer and a underlay iron.
During the operation, beat around the heated area quickly to increase the compressing stress
and the contraction till that area is smoothed. The wooden hammer is preferred and do not use
too strong a force, or the metal panel may get re-stretched.
4.3. Restoration of Cutting & Patching
When any part of the metal door panel is eroded or damaged beyond repair, it should be removed and
replaced with a new piece by welding. The repairing methods include patching repair and cutting.
Procedures for cutting repair are as follows:
(1) Check the damaged part and determine the repairing area.
(2) Make a paper model according to the determined area.
(3) Draw lines on the metal plates and cut material according to the paper model, and leave proper
processing allowance.

(4) Select proper processing and shaping methods so that the patch matches well with the part to be
removed.
(5) Apply the patch to the intended position and press it tightly, draw a line along the edge of the part
to be removed and cut it out, using methods like gas cutting or excising according to the actual
situation, and then align the patch with the excised area.
(6) Weld the seam by gas welding or carbon oxide protection welding. Spot-weld it at a pace of 3050mm to fix it and then weld it again in a certain order after beating it smooth. For seams requiring
welding of higher strength, double-sided welding is preferred.
(7) Smooth the welded seam by beating it with flat hammer, release the welding pressures, and then
shape it and polish the seam with a grinding machine.
4.4. Restoration of Wrinkled Parts
Depending on the damage extent of the plate work pieces, the wrinkles are divided into “live wrinkles”
and “dead wrinkles”. The “live wrinkles” are slight ones and can be directly removed by beating the
convex part with a hammer. The “dead wrinkles” refer to seriously damaged parts. Since the wrinkles
are folded and pressed against each other, so if you hammer the most convex part, the wrinkles would
get even more seriously and harder to release, hence the name “dead wrinkles”. The principle of
correcting the wrinkles is to spread “dead wrinkles” first so that they become “live wrinkles”, and then
“live wrinkles” are converted into convex-concave shape, and finally restore the damaged parts just as
you deal with convex-concave damages. The repairing procedures are as follows:
(1) First use support-draw method to apply a correcting force in the direction opposite to that of the
impact at the wrinkled part of the plate work, and then spread and ease the wrinkles.
(2) Remove the wrinkled plate work and lay it on a platform and then, beginning with the inner side of
the wrinkled area, pry up the wrinkles with a proper prying tool and heat the “dead wrinkles” one by
one with a welding torch at the same time. Finally all “dead wrinkles” are pried up and eased and
converted into” live wrinkle”.
(3) Beat and smooth the “live wrinkles” from the inner side outward. The hammered spots should be
near the most convex part of the “live wrinkles”. At the same time make sure the platform can
support every beaten spot. When the wrinkles in one side of the plate are almost smoothed, turn it
over to beat the other side till all wrinkles are completely spread out.
(4) Measure with a templet, and at the same time heat and beat the convex-concave part to restore it
to its original shape.
(5) When the vehicle body is assembled, test with a templet again and make finer correction to
achieve the final requirements.
(6) The seriously damaged wrinkles that can not be restored can be excised and repaired.
4.5. Welding of Four Doors and Two Covers
When welding the door panel, choose proper welding methods: gas welding (oxygen and acetylene
welding), CO2 shielded welding, manual arc welding, resistance spot welding, braze welding and so on.
Besides, in order not to reduce the original strength and durability of the vehicle body, try to adopt the
welding methods used in manufacturing the door panels, and the dimensions and types of all weld
joints should be similar to those used by the original manufacturer.
As for appearance and quality, no burnt-through spots, half points, cracks, a lot of burrs or other defects
should exist at the welded parts. The welded surface should be smooth and nice-looking, no obvious
twist or deformation is allowed, and the indentation depth should be less than 1/5 of the plate thickness.
Flat spade and iron hammer can be used to carry out non-destructive tests of the welded spots’
strength. Insert the flat spade between two welded spots to see if they are easy to separate, and then
beat the welded part with an iron hammer to restore it. No welding spatter is allowed at the welded
seam, and the overlapped seam should be nice-looking with no defects like air holes or cracks. Defects
like undercut, welding beading and burning through are also not allowed.
