Abstract
The present invention provide a filler metal for TIG welding capable of stable welding, of which heat flux feeding area is wider than conventional wire filler metal and heat input per unit length is increased. The filler metal for TIG welding which is continuously supplied on a base metal to be melted by an arc after forming the arc between the base metal and an electrode over the base metal and supplying shield gas around the arc, wherein the cross-section of the filler metal has curved shape of which surface facing the electrode is concavely curved to the electrode.
