Abstract
Adaptively controlled hybrid laser-arc welding has been demonstrated using a 5kW 6mm.mrad Yb fibre laser. ISO 13919-1 class B (stringent) quality butt welds have been made in 4mm Al alloy, 6mm stainless steel and 8mm thickness steel plates. A laser vision sensor, used to track the joints robotically during welding, sends joint fit-up information (gap width and mismatch height) to a controller. This adjusts, in real time, the welding parameters to increase the net tolerance of hybrid welding, particularly to joint gap. Stringent quality welds can be made over a wider range of joint fit-up cases than using fixed conditions.
