High Single Pulse Energy Stainless Steel Mold YAG Laser Welding Machine

High Single Pulse Energy Stainless Steel Mold YAG Laser Welding Machine


Laser welding machine is mainly used in hole-filling of gold and silver ornaments, spot welding, joint repairing and flaw setting.

YAG Laser Principle

YAG laser welding uses high-energy pulsed lasers to weld workpieces. It uses a pulsed xenon lamp as the pump light source and ND: YAG as the laser working material. The frequency, pulse width, moving speed and direction of the pulsed laser required for welding can be controlled by PLC or industrial PC, and the laser energy can be controlled by adjusting the current, laser frequency and pulse width.

Product Features 

1. Adopting advanced technology and unique overall structure design, it is suitable for the repair of various medium and small molds.
2. Use high-quality ceramic reflectors. It can resist corrosion and high temperature. The service life is as long as 8-10 years. The life of the xenon lamp exceeds 8 million times.
3. The heat-affected range is small, the workpiece will not be deformed, and there is no air hole.
4. It can be welded in a narrow position, the welding is deeper, and it will not hurt the edge. It will not deform the mold.
5. There is no need to modify the mold, which can save a lot of material, labor and time costs.
6. High-definition CCD for clear imaging of samples
7. It can work continuously for 24 hours.
