Disclosed are a filler metal for TIG welding characterized by an aspect ratio of 2 to 80 and having a rectangular-shaped cross section and a TIG welding method using the filler metal. According to the present invention, beads are not easily formed since deviated from an arc center when an existing wire is used at the same electric current, however when a filler metal according to the present invention is used, beads can be formed in a stable manner since an arc area is so large as not to be greatly affected even in the case of deviation from the arc center. In addition, the existing round wires fail to be melted due to a fast feeding speed and low calories being fed or unstable melting results in formation of meandering beads, however the present invention allows stable formation of beads even at low electric currents. |
