A series of summaries
Laser welding of metal: high energy laser pulse is used to locally heat the material in a small area. The energy radiated by the laser is guided by heat transfer to the internal diffusion of the material to melt the material and form a specific molten pool. It is mainly aimed at the welding of thin-walled materials and precision parts. Spot welding, butt welding, overlap welding, seal welding, etc. can be realized, with high depth width ratio and small weld width, Small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, no treatment or simple treatment after welding, high weld quality, no pores, accurate control, small focusing light spots, high positioning accuracy, easy to realize automation.

1. Energy real-time control and various waveform settings bring precision welding quality
2. High stability, high reliability, 24-hour stable operation
3. The energy distribution of welding spot is uniform, which is suitable for spot welding of various complex welds and various devices
4. It can meet the trajectory control of plane and special-shaped graphics such as welding points, lines and circles. The welding programming adopts trajectory programming, which is simple to operate and automatic in the welding process. The welding program can be modified, and the operation and modification authority can be set;
5. With higher electro-optic conversion efficiency, better beam quality and less maintenance cost, it is a perfect substitute for the existing lamp pumped YAG laser 
6. CCD monitoring system, X / Y / Z / u worktable, rotary worktable and special automatic chemical fixture provide perfect processing scheme
