<p>PROBLEM TO BE SOLVED: To provide a welding torch for submerged arc welding, which enables an inner surface weld metal and an outer surface weld metal to be fused together by preventing production of a weld-penetration bent part, in a submerged arc welding method using a small-diameter wire.SOLUTION: A welding torch for submerged arc welding is partially provided with a bent member having a bent part. The bent member is rotated in such a manner that the axial center of the welding torch serves as the center of rotation, and can be fixed to an arbitrary rotational position.</p> |
