Paper Abstract

Sealed CO2 lasers at <500 watts power are widely used for cuttng and drilling, but their welding performance is less well known. The welding trials reported here address this by identifying welding performance for certain widely used ferrous and non-ferrous materials. Welds were made at a fixed average power and a range of laser parameters over a range of weld speeds. Conventional metallographic techniques were used for assessing weld dimensions and weld quality.
