The invention relates to a process for cladding at least one portion of a metal part, the process implementing a non-consumable electrode, a consumable metal filler wire, and an electric arc drawn between the electrode and the part so as to produce a molten metal puddle, the end of the metal filler wire being melted by the electric arc so as to achieve a transfer of molten metal from the filler wire to the molten metal puddle and to coat at least one portion of the part with a metal deposit. According to the invention, the process uses a shielding gas to shield the electrode, the filler wire and the puddle, with a gas mixture containing 20 to 70% helium, and argon for the rest (% by volume). |
