Automotive sheet metal repair method:
Bump damage: the bump of sheet metal parts can be repaired by hammering or jacking, and different treatment methods are adopted in the same situation. Of course, the degree of unevenness is different, and the process flow is different, so we should also consider the material of the body;
Warp and skew deformation. Due to collision, suspension, friction or improper use, sheet metal parts will be warped and skewed. At this time, mechanical method or flame heating tapping can be used to eliminate the damage and deformation of sheet metal parts, and thermal shrinkage method can be used to eliminate the tensile stress and restore the original shape.
Rupture or perforation. For the surface of stamped sheet metal parts modified by damaged goods, the application method can be used to repair them. At present, the main adhesives used are epoxy resin adhesive, phenolic resin adhesive and copper oxide adhesive.
Cracks or local serious damage. In these two cases, in the past, automobile repair was done by welding or repair, but at present, 4S shops usually adopt direct replacement treatment.
