Section 3 Repair After Body Damage The body damage repair includes rectification, reshaping, reinforcing, local change, and complete replacement.
Generally, CO2 welding method is used.I Reshaping Repair1. Rectification
In general, the deformation of body is caused by accident. It can be rectified in a supporting method. In the
rectification process, apply the force in the direction against the force of accident or deformation. In most cases,
cold rectification can be used. Local heating can reduce internal stress, and the corresponding processing shall be
carried out.
For the limousine, it is preferred to rectify it with the dressing machine. All dimensions and tolerances of all
parts shall be returned to the original standard, so the mobility, serviceability and comfortableness can be
guaranteed. (Fig.5-23)Section 2 Typical Technique of Body Panel RepairFig. 5-23 Mounting Bench of Universal Dressing Machine7-16Repair Process Flow:Visual Inspection

The body repair starts from the primary rectification or rough rectification. The deformation can be removed
with the supporting method. The angle of the supporting force shall be close to the angle of the external force that
caused the damage. Apply a counterforce at the back of the pulling force point to adjust the supporting force. Make
measurement on the deformation generated in the supporting process. To remove the internal stress, heat the
corresponding parts. For different rectification methods, see Fig. 5-24.
2. Reinforcement
When the local damage, rupture or crack occurs on various components, repair can be made by reinforcement.
Especially for those parts on which damage occurs frequently, special reinforcement measures shall be taken.
However, random reinforcement or component welding shall be avoided, which may affect the body's status.
The reinforcement includes bushing reinforcement, patching reinforcement, arc inlay, and angle plate reinforcement.
3. Local Removal & New Parts Replacement
For the parts with serious corrosion, they must be removed. For the ruptured parts, they shall be replaced
entirely. For the posts manufactured with thin plate by punch, they shall be ordered from the manufacturer. When
the molding is made independently, all specifications (including material, section dimensions and thickness etc.)
shall meet the original design requirement. For the ruptured post (including cross beam), if it is replaced entirely,
it must be connected in the same manner as that of the original post.II. Repair for Body Outside Plate1. Damage Type
a. Crack & Rupture
In the running process, the body vibrates continuously and burdens the loads. When the vehicle makes accident
acceleration, sharp swerve an emergency brake, the body will keep in an inertial status. When the vehicle runs on
the uneven road, bend and distortion will happen on the body.
Affected by these external forces for a long time, crack and rupture may occurs on the stress concentrated parts
and weak structure on the body outside plate.
The stress mostly concentrate on the corner, hem and narrow part of the outside plate, so crack and rupture often
occur on these parts.
b. Corrosion
The corrosion on the outside plate is mostly caused by the mud and water on the metal surface. Only in special
case, it results from the chemical corrosion by chemicals. When the corrosion occurs, rust may appear on the
outside plate and fall gradually, resulting in a hole. On the skirt outside plate and launder, corrosion usually occurs
on the seams between door and frame and the interlayer between the outside plate and the frame.

In order to improve the body's rigidity, high-strength steel plates are used at many key parts on the body. For
the parts under forces, reinforced measures are carried out. (Fig. 5-36)Fig. 5-36 High-strength Steel Panel

designed with three compartments and five doors. With the same overall length, the space is utilized fully, which
is helpful to arrangement of passengers. (Fig. 5-35)
