Nowadays, laser welding has become a trend in automobile body production. The use of laser welding in automobile manufacturing can not only reduce the weight of the car body and improve the assembly accuracy of the car body, but also greatly enhance the strength of the car body. Provide higher security. The following introduces the application of laser welding machine in the field of automobile manufacturing.

The laser welding machine also greatly improves the structural precision of the body during seamless welding. 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 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. 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;

2. Body welding: In-line laser welding in the automotive industry is widely used in the assembly and connection of body stamping parts. The main applications include the laser welding of the roof cover, the laser welding of the trunk lid and the laser welding of the frame; another important application of the laser welding of the body 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.

3. 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.

The above is the application of handheld laser welding machine in the field of automobile manufacturing. The laser welding machine for auto parts adopts intelligent operation of robots, collimates parallel light through a collimating mirror, and focuses on the workpiece to implement welding. With a simple universal instrument, it can perform flexible transmission non-contact welding for welding precision parts that are difficult to access to large molds, with greater flexibility and operability.
