Laser welding machine, also commonly known as laser welding machine, laser welding machine, is a laser material processing machine, which is divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine, fiber transmission laser welding according to its working mode. Machine welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool for welding purposes.
Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation spreads through the heat to the inside of the material, melting the material to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lamination welding, sealing welding, etc., with high aspect ratio, small weld width and small heat affected zone. The deformation is small, the welding speed is fast, the weld seam is flat and beautiful, no need for treatment after welding or simple processing, the weld seam has high quality, no pores, precise control, small focusing spot, high positioning precision and easy automation.
