Laser welding has the advantages of high accuracy, clean and environmental protection, diverse processing materials and high efficiency, and is widely used in high-end precision manufacturing fields such as automobile industry. Today we will introduce the application of laser welding technology in the automobile industry.

The application of laser welding in the manufacturing process of automobile industry mainly includes three types: laser assembly welding of body assembly and sub-assembly, laser tailor welding of plates with different thickness, and laser welding of automobile parts.

Laser welding of car body mainly includes assembly welding, welding of side wall and top cover, and subsequent welding. On the one hand, using laser welding in the automobile industry can reduce the weight of the car, improve the mobility of the car, and reduce fuel consumption; On the other hand, improve the quality of products and progressiveness technology.

Laser tailor-welding is to connect plates of different thickness, different materials, different or the same performance into a whole through laser cutting and assembly technology according to different design and performance requirements of the body during the design and manufacturing of the body, and then press them to form a part of the body. At present, 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 cover, the side wall inner plate, the door inner plate, the front floor, the front longitudinal beam, the bumper, the crossbeam, the wheel housing, the B-pillar connector, the middle column, and so on.

Laser welding of automobile parts has the advantages of almost no deformation of the welding part, fast welding speed, and no need for post-weld heat treatment. At present, laser welding is widely used in the manufacturing of transmission gears, valve tappets, door hinges, transmission shafts, steering shafts, engine exhaust pipes, clutches, supercharger axles and chassis and other automotive components.
