Abstract

In a process for automatic or semi-automatic welding, where a coil of wire is fed continuously to the weld through the centre of a gas flame which melts the wire and heats the workpiece, an electric voltage is applied between any point on the component carrying the welding wire and the workpiece so that a heating current travels through the wire. The voltage is pref. applied either between the burner nozzle and the workpiece or between the wire feed rolls and the workpiece. The heat applied to the welding wire can be varied to suit the wire dia. and/or its speed without having to alter the gas flame.
