The invention concerns a method of surfacing at least one portion of a metal part (8), said method implementing a non-consumable electrode (4), a consumable metal filler wire (1), and an electric arc (5) established between the electrode (4) and the part (8) in such a way as to produce a molten metal bath (2), the end of the metal filler wire (1) being melted by the electric arc (5) in such a way as to produce a transfer of molten metal from the filler wire (1) to the molten metal bath (2) and to coat at least a portion of the part (8) with a metal deposit (6). The method implements a gas protection of the electrode (4), the filler wire (1) and the bath (2), with a gas mixture consisting of 20 to 70 % helium, the remainder consisting of argon (% by volume). |
