ABSTRACT:
A method of welding metal products, at least one of which is made of nickel or a nickel alloy, comprises the steps of generating an arc between the products to be welded, serving as a positive pole, and a tungsten electrode held by a welding torch, serving as a negative pole. A shielding gas is emitted, consisting of an argon-based mixed gas containing one or both of hydrogen and helium, from a confining gas nozzle concentric with the tungsten electrode, thus confining the apparent flaring angle of the arc within 80 degrees. The welding torch is moved along the weld line while feeding the tip of a filler wire to a part of the molten pool directly below the arc. This method is applicable to the welding of metal products, at least one of which is made of nickel or a nickel alloy.
