The Laser Welding Process

 

Deposition welding with solid-state lasers offers an economical alternative to standard welding options.
W
ith the laser, parts are repaired or modified quickly, economically and with high quality.
The laser beam is focused to a small spot and the energy input controlled to a high level of precision.
This enables delicate welds with minimal heat introduction.
The material deposited with the laser is extremely durable, dense and has good penetration.

 

An Nd:YAG laser is used as the heat source.
The high power density of the pulsed Nd:YAG laser welding process yields the lowest heat fusion welding process available to industry.

The welding is accomplished by the placing of filler wire between the work piece surface and the laser beam. The laser beam melts the filler material with the parent metal yielding a built up of the surface.

The wire diameter used is typically between 0.1mm & 0.5mm.

Fusion welding (no filler rod) is also used in the assembly of components in a range of industries.

The Laser diameter (weld width) is between 0.3mm to 1.5mm.
