Laser welding machine is widely used in high-end precision manufacturing fields such as automobile industry due to its advantages of high accuracy, clean and environmental protection, diverse processing materials and high efficiency. Today we will introduce the application of laser welding technology in the automobile industry.
The application of laser welding machine in the manufacturing process of automobile industry mainly includes three types: laser assembly welding of body assembly and sub assembly, laser tailor welding of unequal thickness plates, and laser welding of automobile parts.
1. Laser welding machine of vehicle body mainly includes sub assembly welding, side wall and top cover welding, and subsequent welding. On the one hand, laser welding in the automotive industry can reduce vehicle weight, improve vehicle mobility, and reduce fuel consumption; On the other hand, improve the quality of products and progressiveness technology.
2. Laser welding machine is to connect plates of different thickness, different materials and different or the same performance into a whole through laser cutting and assembly technology according to different design and performance requirements of the vehicle body in the design and manufacturing of the vehicle body, and then press to form a part of the vehicle body. At present, the laser tailor welded blanks have been widely used in various parts of the car body, such as the trunk reinforcement plate, the trunk inner plate, the shock absorber support, the rear wheel housing, the side inner plate, the door inner plate, the front floor, the front longitudinal beam, the bumper, the cross beam, the wheel housing, the B-pillar connectors, the center pillar, etc.
3. Laser welding machine for automobile parts has the advantages of almost no deformation of welding parts, fast welding speed, and no post weld heat treatment. At present, laser welding is widely used in the manufacturing of automotive components such as transmission gears, valve tappets, door hinges, transmission shafts, steering shafts, engine exhaust pipes, clutches, supercharger axles and chassis.
