The seamless welding of the laser welding machine greatly improves the structural precision of the body.
When the car is driving, due to the bumps and squeezing of the ground, every component and structure is subjected to different degrees of impact, which requires a high precision and strength of the overall structure of the car.
Using the current laser welding technology, its dynamic and static stiffness can be improved by more than 50% compared with other welding processes, which reduces the noise and vibration during driving, improves the ride comfort, and also improves the safety performance of the car.
1. Body welding: Online laser welding in the automotive industry is widely used in the assembly and connection of body stamping parts. The main applications include laser welding of roof cover, trunk lid laser welding and frame laser welding; another important body laser welding application is the laser welding of body structural parts (including doors, body side frame and pillars, etc.) . The reason for using laser welding is to improve the strength of the body and to solve the problem that conventional resistance spot welding is difficult for some parts.2. Unequal thickness laser welded blanks: The use of unequal thickness laser welded blanks in car body manufacturing can reduce the weight of the car body, reduce the number of parts, improve safety and reliability and reduce production costs;
3. There are also welding of gears and transmission parts. In addition, various parts of the gearbox can be welded on this equipment, especially the differential case and drive shaft in the car gearbox, which are often joined and welded after the production of a single part. made. Nowadays, the application of laser welding in automobile body production has become a trend. The use of laser welding can not only reduce the weight of the body and improve the assembly accuracy of the body, but also greatly enhance the strength of the body, providing users with higher comfort while enjoying the comfort. security.
