What is Sheet Metal Repair

Sheet metal repair, also called cold working, is one of the important means of automobile repair technology.

Refers to post-collision body repair, that is, all other work except body anti-corrosion and decorative spraying.

Such as body damage analysis, body measurement, body sheet metal forming, tensile correction, stress relief welding, body accessory assembly adjustment, etc.

To put it bluntly, if the exterior of the car body is damaged or deformed, sheet metal processing is required.

Maintenance personnel must not only know the technical parameters and dimensions of the car body, but also master the material characteristics of the car body, the transmission of stress characteristics, the deformation trend and stress points of the car body, and the production process of the car body such as welding processes, etc.

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 or indirect damage and deformation of the vehicle body, as well as the hidden dangers caused by the vehicle body deformation, and formulate a complete vehicle body repair plan.

Then with the help of correct repair technology and accurate weighing of the three-dimensional data of each key point, the key points of the car body can be restored to their original positions, and the damaged car body can be restored to its factory condition.

Sheet metal repair is not simply about tapping the car's sheet metal. The quality of the repair cannot be judged by the naked eye on the car's appearance and cracks.

This requires the repairman not only to be very familiar with the technical parameters and dimensions of the vehicle, but also to master the material structure of the vehicle body, the stress and deformation trend of the vehicle body, and the welding process of the vehicle body, etc.

This is a very delicate technical job that requires the operator's patience and meticulousness to complete.
