Laser welding machine is a thermal processing process that uses a laser beam as a heat source. Compared with electron beam plasma beam and general mechanical processing, it has many advantages. The laser focal spot of the laser beam is small and the power density is high, which can weld some alloy materials with high melting point and high strength. Laser welding is a non- contact process, and there are no problems such as tool wear and tool exchange.
The laser welding machine performs deposition, hole sealing, filling and other repair functions for the wear, scratches, pinholes, cracks, defect deformation, hardness reduction, sand holes and other defects of molds and metal workpieces. After the repair, the substrate will not be deformed, annealed, undercut or residual stress, and its metal structure will not be changed. The repair accuracy is high, and the coating thickness is from a few microns to a few millimeters, and only needs to be polished. High-power argon protection, can work for a long time. The laser beam energy is adjustable, the moving speed is adjustable, and various welding processes are possible. Laser welding has a high degree of automation and can be controlled by a computer. It has fast welding speed and high efficiency, and can easily weld any complex shape.
