Laser welding machine has the advantages of high accuracy, clean environment, various types of processed materials and high efficiency. It is widely used in high-end precision manufacturing fields such as the automotive industry.
Now, let’s introduce the application of laser welding process in automotive industry. It includes three main types of manufacturing processes: laser assembly welding of body assemblies and sub-assemblies, laser assembly welding of unequal thickness plates, and laser welding of automotive parts.
Laser welding of body is mainly divided into assembly welding, welding of side and top cover, and follow-up welding. The use of laser welding in automotive industry can on the one hand reduce the weight of the car, improve the mobility of the car, and at the same time reduce fuel consumption; on the other hand, improve the quality and technical advancement of the product.
Laser assembly welding is in the body design and manufacturing, according to the different design and performance requirements of the body, different thickness, different materials, different or the same performance of the plate through the laser cutting and assembly technology connected into a whole, and then by stamping and forming for a body part. At present, laser assembled welding plate has been widely used in various parts of auto body, such as luggage box reinforcement plate, luggage box inner plate, shock absorber support, rear wheel cover, side circumference inner plate, door inner plate, front floor, front longitudinal beam, bumper, cross beam, wheel cover, B-pillar connector, center column, etc.
Laser welding of automotive parts has the advantages of almost no deformation of the welded parts, fast welding speed, and no post-weld heat treatment. At present, laser welding is widely used in the manufacture of transmission gears, valve tappets, door hinges, drive shafts, steering shafts, engine exhaust pipes, clutches, supercharger axles and chassis and other automotive parts.
In response to the demand for laser welding machine in automotive industry, MRJ Laser has developed a new robotic laser welding system, which usually adopts high-poser fiber lasers over 2000W, high efficiency of photoelectric conversion and long working life. Besides, it has Intelligent manipulator operation and unique wobble welding module. Depending on collimating the laser beam and focusing on the workpiece, robotic laser welding system is easily able to implement flexible transmission with non-contact welding, so as to achieve more precise and perfect welding.
Core advantages
- Improved appearance and internal quality of welds
- Improved labor intensity of workers and can work in harmful environment
- Reduce the requirements for workers’ skills while improve production efficiency
- Shorten the preparation period of product upgrading and save production cost and time
