Therefore, it is necessary to repair the damaged parts to ensure the normal use and safety of the vehicle. Automobile maintenance is a general term for automobile maintenance and repair. It means to detect an accident-prone automobile through technical means, find out the cause of the fault, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard. Automobile maintenance refers to the restorative repair that uses the method of repairing or replacing any parts of the automobile to restore the good technical condition of the automobile and fully restore the life of the automobile.

[0003] During the maintenance of an automobile, the situation of parts fracture may occur. In order to facilitate the subsequent welding repair of the parts, it is generally necessary to disassemble the parts to be welded and then perform welding treatment on them. However, there will be certain stress inside the fractured automobile parts. If welding treatment is directly carried out on them, it is easy to cause unstable welding positions, welding fractures or cracks in the welds in the later stage. Summary of the Invention
