description The invention relates to a method for welding alloy steels or non-alloy steels using continuous-wave CO2 laser welding, comprising the blowing-in of a shielding gas in order to protect the molten metal from the action of the air, characterised in that the said shielding gas is a mixture of helium and argon, comprising 18 to 55% by volume of helium with respect to the total volume of helium and argon. Use for the welding of all types of steel.
