Types of laser welding machines Laser welding machine is also often known as laser cold welding machine, laser argon welding machine, laser welding equipment, etc. According to its working method, it can often be divided into laser mold welding machine (manual laser welding equipment), automatic laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine, galvanometer welding machine, handheld welding machine, etc., special laser welding The equipment includes sensor welding machine, silicon steel sheet laser welding equipment, keyboard laser welding equipment. Working Principle Laser welding is the use of high-energy laser pulses to locally heat the material in tiny areas. The energy of laser radiation diffuses into the material through thermal conduction, melting the material 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. It can realize spot welding, butt welding, stack welding, sealing welding, etc. It has a high aspect ratio, a small weld width, and a small heat affected zone. Small deformation, fast welding speed, smooth and beautiful weld seam, no or simple processing after welding, high quality weld seam, no air holes, precise control, small focus spot, high positioning accuracy, easy to automate.
