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

The application of laser welding in the manufacturing process of the 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.

Laser welding of car 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 the weight of the car, improve its mobility, and reduce fuel consumption; On the other hand, improve the quality of products and progressiveness technology.

Laser tailoring welding is the process of connecting plates of different thicknesses, materials, or properties into a whole through laser cutting and assembly technology, based on different design and performance requirements of the vehicle body, and then stamping to form a certain component of the vehicle body.

At present, laser welded blanks have been widely used in various parts of the car body, such as the trunk reinforcement plate, trunk inner plate, shock absorber support, rear wheel cover, side wall inner plate, door inner plate, front floor panel, front longitudinal beam, bumper, crossbeam, wheel cover, B-pillar connector, center pillar, etc.

Laser welding of 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 parts such as transmission gears, valve tappets, door hinges, transmission shafts, steering shafts, engine exhaust pipes, clutches, supercharger axles and chassis.
