Principle: Laser welding is to use high-energy laser pulses to locally heat materials in a small range. The energy of laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new welding method, which is mainly used for welding thin-walled materials and precision parts, and can realize spot welding, butt welding, overlapping welding and sealing welding. It has the advantages of high thickness ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld, no treatment or only simple treatment after welding, high weld quality, no porosity, accurate control, small focused light spot and high positioning accuracy.
Type: Laser welding machine is usually called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser cold welding machine, laser argon arc welding machine and laser welding equipment. According to its working mode, it can often be divided into laser mold welding machine (manual laser welding equipment), automatic laser welding machine, jewelry laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine, galvanometer welding machine, hand-held welding machine and so on. Special laser welding equipment includes sensor welding machine, silicon steel sheet laser welding equipment and keyboard laser welding equipment.
