Abstract

A member (17) is provided with a welded facing by means of a method in which a strip electrode, the strip width of which is at least 12 times larger than the strip thickness, is fed and melted under gas shielding by means of a transmitted open arc. A feed device (10) moves the strip electrode at a constant, adjustable speed down through a welding head (15) with electric contact means (31, 32) and further towards the member, a power source at the same time supplying a voltage and current so that the electrode material is melted in a spray arc or a short arc. The melted material is shielded by gas supplied via an annular gas distributor nozzle (46, 49) positioned inside a gas cup (48), which may suitably have an outlet opening which is oblong in the welding direction. The welding is performed at a melting rate of about 8 kg/h, and the method is particularly applicable for welding a protective facing on to members of an irregular geometry, such as a disc valve (17) for an internal combustion engine.
