The Working Principles of Laser Welding Machine

Mar 05, 2020

Laser welding machine is a machine for laser material processing. According to its working mode, laser welding machine can be divided into laser mold welding machine (manual welding machine), automatic laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine. The high-energy laser pulse locally heats the material in a small area. The energy radiated by the laser is diffused to the inside of the material through thermal conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding.

Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation is diffused into the material through thermal conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for thin-wall materials and precision parts. It can realize spot welding, butt welding, overlay welding, seal welding, etc., with high aspect ratio, small weld width, small heat-affected zone Small deformation, fast welding speed, smooth and beautiful welding seam, no treatment or simple processing after welding, high welding seam quality, no air holes, precise control, small focused light spot, high positioning accuracy, easy to realize automation.
