automatic laser welding machine is an automatic welding equipment, which uses high-energy laser pulse to locally heat the material in a small area. The energy of laser radiation is guided to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool. Mainly for the welding of thin-walled materials and precision parts, it can realize spot welding, butt welding, overlap welding, seal welding, etc. it has the characteristics of small weld width, fast welding speed, high weld quality, no pores, accurate control, high positioning accuracy, easy automation, etc.
