ABSTRACT:
A method according to the invention comprises fixing a consumable electrode (1) with respect to a current carrying device (2), positioning it over a surface (4) of a part (5) to be fused, firing a welding arc (8) between the end face (3) of the electrode (1) and the surface (4) of the part (5). The electrode (1) is then fed to a fusion space (9) by swiftly bringing the current carrying device (2) close to the surface (4) of the part (5) at a speed exceeding the rate of fusion of the electrode (1).
