How to car body dent repair serious damage for car

The car body is damaged, and the repair plan for different parts of the damage is different. In the editor, I have summarized the repair and repair plan for different damaged parts of the car body for everyone. I hope it will be helpful to everyone.

(1) Overall repair plan

① When the body is seriously damaged, the overall damage of the body exceeds 30%, or the bottom plate is severely deformed, the whole body cannot be repaired, and the whole body can be replaced according to the user's needs.

②Remove all available assemblies and parts from the broken car, and conduct a comprehensive inspection and repair of the main assembly such as the engine.

③ Replace with a new car body assembly and all parts that need to be replaced, and re-assemble according to the original factory process.

(2) Local severe collision repair plan

① When the vehicle body collides, if the damage only occurs locally, such as the front and rear fenders, doors, engine compartment cover or luggage compartment cover, partial replacement of the vehicle body can be carried out, saving trouble, time and cost.

② For damaged body sheet metal parts, depending on the degree of damage and the relevant requirements of the vehicle for repairing parts, it is determined to be repaired separately or scrapped.

(3) Repair plan for moderate damage to the body

① When the vehicle body is moderately damaged, it involves the deformation of the underbody, but there is no need to replace the whole body. The underbody correction and body correction should be carried out first, and then the damaged body sheet metal parts should be repaired.

②The calibration of the vehicle body floor has been completed to ensure the three-dimensional position of the vehicle body floor, the overall position of the car body, the placement of the engine assembly and the front suspension, and the restoration of the positioning angle of the car and the positioning of other assemblies.

③After the body bottom plate is corrected, the body sheet metal repair is carried out.

(4) Repair plan for serious damage to the side of the car body

① During a crash, the side of the vehicle body was severely damaged, causing one side of the vehicle body to dent and deform.

②When the collision force is large, the side deformation of the body may be transmitted to the body from one side, causing serious deformation of the body floor, which may be transmitted to the top cover, and the top cover may be deformed. Even from the underfloor and roof of the vehicle body to the other side, the side surface of the vehicle body is raised, and the correction method should be used to restore it to its original shape.

③When one side of the threshold is seriously deformed and the underbody is involved, the sill shall be pulled by the traction method. Since the A and B pillars of the general body are made of high-strength steel, once damaged, the pillars must be replaced.

④ The damaged section of the pillar should be cut off by sawing or gas welding according to the cutting size on the maintenance parameters, and the relevant parts should be corrected. For example, the pillar damage may involve the deformation of the top cover and the body floor. The deformation of the area is restored, and then a section of pillars with exactly the same rules and shapes can be replaced.
