The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly aimed at the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, lap welding, sealing welding, etc., with high depth-to-width ratio, small weld width, and small heat-affected zone. The deformation is small, the welding speed is fast, the weld seam is smooth and beautiful, no treatment is required or only simple treatment is required after welding, the weld seam quality is high, there is no air hole, it can be precisely controlled, the focusing light spot is small, the positioning accuracy is high, and it is easy to realize automation. Laser welding machines can be divided into several types according to their working methods.
What types and forms of laser welding machines are there? According to its working mode, it is divided into: laser mold welding machine (manual laser welding equipment), automatic laser welding machine, jewelry laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine, galvanometer welding machine, hand-held welding machine, etc. , Special laser welding equipment includes sensor welding machine, silicon steel sheet laser welding equipment, keyboard laser welding and other equipment.
