Laser welding machine can weld carbon steel, die steel, carbon steel, stainless steel, titanium, nickel, tin, copper, aluminum, chromium, niobium, gold, silver and other metals and their alloys, also can meet the laser welding between different steel. Laser welding is the use of high-energy laser pulses to heat fine areas of the material. The laser radiation energy diffuses into the material by heat conduction, melting the material and creating a specific dissolution pool. It is a new type of welding method, mainly used for welding thin-walled materials and precision parts. Welding, butt welding, stack welding and seal welding can be realized. High depth to width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, neat and beautiful welding, and no treatment or simple solution after welding. High quality of weld seam, no porosity, and can be precisely controlled. Laser welding machine is also called laser welding machine, kinetic energy negative feedback laser welding machine, lightning welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc. According to its working mode, it is usually divided into laser mold welder (manual laser welding equipment), automatic laser welder, jewelry laser welder, laser spot welder, fiber special laser welding equipment including sensor welder, silicon steel sheet laser welding equipment, keyboard laser welding equipment, etc.
