Nowadays, laser welding has become a trend in the production of automobile body. The use of laser welding in automobile manufacturing 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. Provide higher security. The following is an introduction to the application of laser welding machine in the field of automobile manufacturing.
The laser welding machine makes the structural precision of the car body greatly improved during seamless welding. When the car is driving, due to the bumps and squeezing of the ground, each component and structure are subjected to different degrees of impact, which requires the overall structural precision of the car to be very high. With 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 comfort of riding, and also improves the safety performance of the car.
1. Unequal thickness laser tailor-welded blank: The use of unequal thickness laser tailor-welded blank in body manufacturing can reduce body weight, 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 laser welding of roof cover, laser welding of trunk cover and laser welding of frame; another important application of body laser welding is laser welding of body structural parts (including doors, body side frames and pillars, etc.). The reason for using laser welding is that it can improve the strength of the car body and solve the problem that it is difficult to implement regular resistance spot welding in some parts.
3. Gear and transmission parts welding. In addition, a variety of parts of the gearbox can be welded on this equipment, especially the differential housing and drive shaft in the car gearbox, which are often joined and welded to each other after the production of individual parts.
The above is the application of laser welding machine in the field of automobile manufacturing. The laser welding machine for auto parts adopts robot intelligent operation, collimates parallel light through a collimating lens, and focuses on a laser equipment for welding on the workpiece. With a simple universal instrument, it can implement flexible transmission non-contact welding for welding precision parts that are difficult to access to large molds, and has greater flexibility.
