The pulsed Nd:YAG laser welding process is very unique in that it is the lowest heat input fusion welding process available to the industry and thus yields no/minimal distortion of the workpiece. The laser beam is focused down to a very small diameter onto the workpiece and melts the materials to be joined at the joint interface. It can be used to weld foils as thin as 0.001″ thick. Weld penetration can be up to 0.060″ deep.
A variety of specialty materials including kovar, 21-6-9, tool steels, and refractory alloys have also been welded.
Filler wire system which automatically feeds 0.006″- 0.020″ diameter filler wire into the weld pool during laser welding. This allows control of weld metal chemistry that prevents weld cracking on difficult to weld metals. This is the only filler wire feed system in the country which has been coupled to a pulsed Nd:YAG laser welding system.
