Automotive sheet metal is also called cold working. To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is needed. Automobile collision repair has developed from the initial "welding repair" to the secondary manufacturing and assembly of the car body. The repair of vehicles in collision accidents is no longer a simple automotive sheet metal knock, and the quality of repair can not be observed only by naked eyes.
Extended data:
1, automotive sheet metal maintenance personnel should not only know the technical parameters and dimensions of the car body, but also master the characteristics of car body materials, the deformation trend of the car body, the transfer of stress points and the welding process. On the basis of mastering this knowledge, maintenance personnel should also use advanced measuring tools to accurately measure three-dimensional shapes.
2. automotive sheet metal's technology should judge the direct and indirect damage and deformation of the car body and the hidden dangers caused by the car body deformation, formulate a complete car body repair scheme, and then cooperate with the correct maintenance technology and accurate three-dimensional data of key points to restore the car body key points to their original positions and restore the damaged car body to the factory state.
3, because the car is a sophisticated whole. Moreover, electrical accessories and mechanical accessories should be attached to the corresponding positions of the car body with high precision and low error. Even the straightness and curvature of car paint are highly dependent on the error value of car body sheet metal. Therefore, sheet metal body repair and repair have become purely manual work in the automobile industry without hard standards, automatic tools and intuitive teaching.
4. The car body assembly includes: car body sheet metal, car glass, car lights, car interior and exterior decorative parts and handles, seats and accessories, car lock mechanism, window sealing and lifting mechanism, door and front and rear sail cover connecting and moving mechanism. That is to say, when the car owner has problems such as broken glass, broken door locks and damaged decorative parts, remember to look for automotive sheet metal instead of other jobs.
