Principle Of Laser Welding

- Mar 16, 2019-

The laser welding machine uses a high-energy laser pulse to locally heat the material in a small area. The energy of the laser radiation spreads 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. Laser welding is mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, stack welding, sealing welding, etc. The aspect ratio is high, the weld width is small, and the heat affected zone Small, small deformation, fast welding speed, smooth and beautiful weld seam, no need for treatment after welding or simple treatment, high weld quality, no air holes, precise control, small focus spot, high positioning accuracy and easy automation.
