In the process of automobile body design and production technology manufacturing, laser welding is one of the important process methods in automobile company manufacturing. The use of laser welding can make the combination precision higher, reduce the weight of the vehicle body, greatly increase the rigidity and strength of the car shell, thus reducing the hidden danger in the car and providing higher security. It can also reduce noise and improve safety and comfort.
Nowadays, laser welding has become a trend in the production of automobile bodies. Here is an introduction to the application of laser welding machines in the field of automobile manufacturing.
Due to the bumping and squeezing of the ground when the car is driving, each part and structure are subject to different degrees of impact, which requires the overall structure of the car to have high precision strength. With the current laser welding technology, its dynamic and static stiffness can be improved by more than 50% compared with other welding processes, reducing the noise and vibration during driving, improving the ride comfort, and improving the safety performance of the car.
- Unequal thickness laser tailor welded blanks: the use of unequal thickness laser tailor welded blanks for body manufacturing can reduce the body weight, reduce the number of parts, improve safety and reliability, and reduce production costs;
- 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 cover and frame; Another important application of laser welding for vehicle body is the laser welding of vehicle body structural parts (including doors, vehicle body side frame and pillar). The reason for using laser welding is that it can improve the strength of the car body and solve the problem that some parts are difficult to implement conventional resistance spot welding.
- Welding of gears and transmission parts. In addition, various parts of the gearbox can be welded on this equipment, especially the differential housing and drive shaft in the car gearbox, which are often formed by connecting and welding individual parts after production.
The above is the application of laser welding machine in the field of automobile manufacturing. The laser welding machine for automobile accessories uses robot intelligent operation, collimates parallel light through a collimating mirror, and focuses on the workpiece to carry out welding. With a simple universal instrument, the flexible transmission non-contact welding can be carried out for the welding precision parts that are difficult to access to large molds, which has greater flexibility.
