Most of the automotive body sheet metal parts are mass-produced, and the forming process is completed on mechanical equipment. Manual operation is mostly auxiliary fabrication, but single-piece fabrication or repair is mainly manual operation. The common manual processes of sheet metal production include bending, edge closing, edge laying, edge pulling, arching and crimping, seaming and correction, etc. At the same time, the permanent connection between the various sheet metal parts is realized by welding, splicing and other methods.
During the use of the vehicle body sheet metal parts, various damages will occur. Common ones are: wear, corrosion, fracture, unevenness or tearing of the metal plate surface, wrinkles, bending and twisting, etc.
Damages during the use of vehicles include: wear, corrosion, cracks, etc.; mechanical damages include: bumps, tears, wrinkle skirts, bending and twisting caused by accidents; sometimes due to design reasons, such as structural strength If it is not enough, the process design is unreasonable, and it will also cause damage to the sheet metal parts.
When car sheet metal parts are damaged, there are often more than one damage. Therefore, when repairing, it should be observed and analyzed, and different repair methods and sequences should be used for different damage conditions in order to obtain satisfactory results.
