Car body shell is a complex structural parts, which is made of more than 100 species, or even hundreds of sheet metal stamping parts, and connected and formed by welding, riveting, mechanical bonding and bonding methods. The body stamping parts are mostly made of Low-carbon steel materials with good weldability. Welding is the most widely used method of body manufacturing in the modern auto industry.


2. Basic process:

2-1, body skeleton welding process

3. The welding joining jigs and fixtures of different models of vehicles can not be shared between one and another, so every new model of vehicle to be added to the assembly plant, one more set of corresponding welding joining jigs and fixtures shall be added, and of course, some other equipment, such as the welding machines can be shared between two welding lines.
