The working principle of laser welding machine

Laser welding is the use of high-energy laser pulses to locally heat the material in a small area, and the energy of 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 for the welding of thin-walled materials and precision parts, can realize spot welding, butt welding, overlay welding, sealing welding, etc., high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth weld seam, beautiful appearance, no treatment or simple treatment after welding, high quality of weld, no pores, precise control, small focused light spot, high positioning accuracy, easy to achieve automation.
