ABSTRACT:
A welding tool is inserted into an object in a rotation-stopped state, and the welding tool is rotated after insertion, thereby the object is stirred by frictional heat. The welding tool is inserted into the object free of whirling. The welding tool can be prevented from inserting in a position shifted from the target welding position. Namely, the welding tool is precisely inserted in the target welding position and members of the object can be welded in the target welding position free of shifting.
