Automobile sheet metal is a technical means of automobile repair. In this regard, automobile sheet metal is automobile sheet metal repair. It refers to the repair of the car body after a collision, which is also equivalent to all the other work except for the anti-corrosion and decorative spraying of the car body. . Such as automobile body damage analysis, automobile body measurement, automobile body sheet metal shaping, tensile correction, stress relief welding, and automobile body accessory assembly and adjustment.

Automobile sheet metal parts are a processing method for automobile maintenance, also called cold work. To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is required. Automobile collision repair has developed from the original "smashing, pulling and welding repair" to secondary body manufacturing and assembly. The repair of a vehicle in a collision accident is no longer a simple matter of tapping on the sheet metal of the car, and the quality of the repair cannot rely solely on observing the appearance and flaws of the vehicle with the naked eye.

Maintenance personnel must not only understand the technical parameters and dimensions of the car body, but also master the material characteristics of the car body, the transmission of force characteristics, the deformation trend and stress points of the car body, and the production process of the car body, such as welding processes. On the basis of mastering this knowledge, maintenance personnel must also use advanced measurement tools and precise three-dimensional measurements of the vehicle body to determine the direct and indirect damage and deformation of the vehicle body, as well as the hidden dangers due to vehicle body deformation, and formulate a complete vehicle body Repair plan, and then use accurate repair technology and accurate three-dimensional dimensional data that meet the critical points to restore the key points of the car body to its original position, and restore the damaged car body to the condition when it left the factory.

Main processes of sheet metal work:

The important processes of sheet metal work can be roughly divided into: car body disassembly, car body calibration, and car body repair.

Each different process can be subdivided into several processes. Two concepts must be discussed during in-depth teaching: automobile work type and automobile body.

The basics of the automobile repair industry can be divided into: mechanical repairmen, electrical appliance repairmen, sheet metal repairmen, and spray paint repairmen. Other accessories, beauty, and special repair industries are not included.

The division of the car body means removing the entire vehicle circuit computer system, removing the entire vehicle engine drive brake steering system, and removing the paint. Then what remains is the body of the car.

Car body assembly (this is a general name for accessories) includes: body sheet metal parts (metal parts) automotive glass, all car lamps, all car interiors, exterior trim parts and door handles, seats and accessories, car locks Mechanism, window sealing and lifting mechanism, the sum of the movable mechanisms connecting the doors and front and rear sail covers. In other words, when your car has problems such as broken glass, malfunctioning door locks, damaged decorative parts, etc., remember that you are looking for automotive sheet metal and not other types of work!

Because the car is a high-precision whole. Moreover, electrical accessories and mechanical accessories must be placed in the corresponding position of the car body with high precision and low error. Even the straightness and curvature of the car paint (which greatly affects the appearance of the car body) are highly dependent on the tolerance value of the car body sheet metal. Therefore, sheet metal bodywork and repair have become a purely manual job in the automotive industry that has no rigid standards, no automatic tools, and cannot be taught intuitively.

In short, automotive sheet metal is the complete repair of faulty and damaged car bodies!
