The technological application of laser welding in the automotive industry

Laser welding has the advantages of high accuracy, cleanliness and environmental protection, various types of processing materials, and high efficiency, and is widely used in high-end precision manufacturing fields such as the automotive industry.

The application of laser welding in the manufacturing process of the automobile industry mainly includes three types: laser group welding of body assemblies and sub-assemblies, laser tailor welding of unequal thickness plates, and laser welding of auto parts.

1. Laser group welding of body assembly and sub-assembly
Body laser welding is mainly divided into assembly welding, side wall and roof welding, and subsequent welding. Using laser welding in the automotive industry can reduce the weight of the car, improve the mobility of the car, and reduce fuel consumption; on the other hand, it can improve the quality of the product. and technological advancement.

2. Laser Tailored Welding of Unequal Thickness Plates
Laser Tailored Welding is in the design and manufacture of car body, according to the different design and performance requirements of the car body, the plates of different thickness, different materials, different or the same performance are connected into a whole by laser cutting and assembling technology, and then stamped into a car body. part. At present, laser welded blanks have been widely used in various parts of the automobile body, such as luggage reinforcement panels, luggage inner panels, shock absorber supports, rear wheel covers, side panel inner panels, door inner panels, front floor, Front longitudinal beams, bumpers, beams, wheel covers, B- pillar connectors, center pillars, etc.

3. Laser welding of auto parts
Laser welding of auto 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 manufacture of transmission gears, valve lifters, door hinges, drive shafts, steering shafts, engine exhaust pipes, clutches, supercharger axles and chassis and other automotive components.
