Sheet metal correction has developed from the initial welding and repair to the secondary manufacturing and assembly of the car body. Maintenance personnel should not only know the technical parameters and dimensions of the car body, but also master the material characteristics of the car body. The stress characteristics convey the deformation trend, stress points and production technology of the car body. Such as welding process.
Matters needing attention in automotive sheet metal processing
After painting, the car paint is not completely dry. If you encounter water, it will affect the paint surface, so try not to touch water a few days before washing the car until the paint is completely dry.
Avoid direct sunlight for 1-2 days after repair, and try not to use it: if the paint is not completely dry, use it. Temperatures such as sunlight and engine heat may crack the paint surface. It is best to put the car in a ventilated and cool place to dry naturally.
