Automotive sheet metal data recovery means quick repair of minor injuries. The sheet metal process is more exquisite than the traditional sheet metal plane leveling, and the effect of direct painting without scraping putty is achieved. The following are related introductions: 1, bump damage: the bump damage of sheet metal parts can be repaired by hammering or jacking, and different treatment methods are adopted for the same situation. Of course, different concave processes are different, and the material of the car body should be considered. 2. Warp and skew deformation: Sheet metal parts will warp and skew due to impact, scraping or improper use. At this time, the damage and deformation of sheet metal parts can be eliminated by mechanical method or flame heating knocking method, mainly the tensile deformation of related parts. The original shape can be restored by eliminating the tensile stress by thermal shrinkage.
