Such as body damage analysis, body measurement, body sheet metal shaping, stretching correction, stress relief welding, body accessories assembly adjustment, etc.
Automotive sheet metal is a processing method of automobile maintenance, 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.
Maintenance personnel should not only know the technical parameters and dimensions of the car body, but also master the characteristics of the car body material, the transmission of force characteristics, the deformation trend and stress points of the car body and the production technology of the car body such as welding technology.
Precautions for maintenance after sheet metal:
1, 1- Try not to get wet or wash the car for 3 days after maintenance.
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.
2. Avoid direct sunlight for 1-2 days after repair, and try not to use it.
If the paint is not dry enough, we will 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.
Step 3 wash the car
When the paint is completely dry, if the car body is dirty, try to suck it clean, otherwise the dirty stains on the car body will penetrate into the paint and cause damage to the paint. It should be noted that you should try not to scrub yourself with a household rag or prepare a detergent with an inappropriate pH value.
The surface of household dishcloth is rough, and if we don't control it well, it will damage the paint surface, and improper pH of detergent will damage the paint surface. If you want to clean yourself, you can wash it with tap water and buy special car washing tools. Be sure to clean and check the tools before driving. Go to the car wash shop and try not to use high-pressure water guns to flush the maintenance parts. The high-pressure water gun has a high pressure, which will cause damage to the car body after a long time.
Step 4 wax
You can wax the car. After waxing, it can effectively prevent dust and harmful substances. It has protective effect on paint surface.
5. Solve the problem in time.
If there are cracks, fading, corrosion marks, water marks, orange peel and other phenomena in the car paint, you must go to the repair shop in time to solve them, and you must not drag them for a long time, which will cause corrosion to the paint surface.
