Laser welding machine, also called laser welding machine, is a thermal processing technology that uses laser beam as heat source. 

Compared with electron beam, plasma beam and general mechanical processing, it has many advantages. The laser beam has a small laser focus spot and high power density, which can weld some alloy materials with high melting point and high strength. Laser welding is a non-contact processing, and there is no problem of tool wear and tool replacement.

The laser welding has a high degree of automation and can be controlled by a computer. The welding speed is fast and the efficiency is high. It can conveniently carry out welding of any complicated shape.
