Principle of laser welding machine

Laser welding uses 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. It is a new type of welding method. Laser welding is mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, and heat-affected zone. Small, small deformation, fast welding speed, smooth and beautiful welding seam, no need to handle or simple processing after welding, high welding seam quality, no air holes, precise control, small focus spot, high positioning accuracy, easy to realize automation.
