Laser Welding Machine

Revolutionizing the Welding Industry

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.

Laser Welder Advantages

  • Fast speed, large depth and small deformation.
  • It can be welded at room temperature or under special conditions, and the welding equipment is simple.
  • It can weld refractory materials such as titanium, quartz, etc., and can weld heterogeneous materials with good results.
  • After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the maximum can reach 10:1.
  • Micro welding is possible. After the laser beam is focused, a small spot can be obtained, and it can be accurately positioned, which can be applied to the group welding of micro and small work pieces in mass automatic production.
  • It can weld hard-to-reach parts and perform non-contact long-distance welding with great flexibility. Especially in recent years, optical fiber transmission technology has been adopted in YAG laser processing technology, so that laser welding technology has been widely promoted and applied.
  • The laser beam is easy to realize the beam splitting according to time and space, and it can perform multi-beam simultaneous processing and multi-station processing, which provides conditions for more precise welding.
