Abstract

A welding method for welding a base metal with a welding wire of specified alloy composition using a TIG welding process, automatically controlling an arc length between a nonconsumable electrode and the base metal, deflecting the arc forward in the welding advance direction by the influence of magnetic fields resulting from DC current flow through the welding wire to prevent arc blow, weaving the arc forward in the welding advance direction by pulsating the current flowing through the weld wire, and heat treating a final weld layer with the nonconsumable electrode.
