Pulsed Nd:YAG Laser Welding System
 

The W series of pulse Nd:YAG laser welding systems are suitable for a wide range of precision spot & seal welding and cutting applications in the electronics, medical, automotive and fine mechanics markets. Typical applications include:

 

· Welding of stainless steel, aluminium alloy and other metals

· Welding of electron guns, titanium capacitors

· Spot welding of optical fiber coupler parts

· Welding of containers

· Seal welding of lithium batteries

 

Laser welding has a number of advantages over conventional techniques including:

 

· low heat input

· reduced distortion

· no mechanical forces

· no tool wear and hence

· consistent weld penetration

 

W series laser welding systems use optical beam delivery. An assistant gas nozzle is also provided. CNC control system provides a convenient programming on the welding/cutting speed, pattern, laser beam on/off, gas on/off. The laser power is adjustable by setting laser pulse width, pulse repetition rate and lamp operation current.

 

A laser welding system typically consists of laser head, switching power supply, CNC control system, beam delivery, motor-driven XY stage & chiller.
