An Nd:YAG laser facility with a maximum average output power of 3kW has been established with the aim of determining the material processing benefits offered at power levels significantly above those available from current commercial Nd:YAG lasers.

Welding trials have been conducted in a wide variety of materials representative of those used in the automotive, aerospace and power generation industries.

Encouraging results have been obtained in overlap and spot welding of zinc coated automotive steels, overlap and butt welding of aluminium alloys and welding of aerospace and structural alloys in thicknesses up to 9.6mm.
