The invention concerns a MIG/MAG-type electric arc welding method that uses a consumable filler wire and gas protection formed by a ternary gaseous mixture comprising 19 to 21% helium, 0.8 to 1.2% CO2 and argon for the remainder (% of volume), in order to weld one or more pieces of stainless steel. According to the invention, the arc is rotary, the consumable filler wire is melted by the arc such as to transfer metal by means of a rotating liquid flow, and the welded parts comprise overlapping ends. |
