<P>PROBLEM TO BE SOLVED: To provide a method for welding a hollow stabilizer with which the toe parts of the weld bead of a weld bead face with a flange for fitting welded and joined to the end part of a hollow stabilizer body are made smooth by single welding stage, and new finishing work for the weld bead face is made unnecessary, the reduction of working man-hours is attained, and whose cost is reduced, and to provide a hollow stabilizer whose welding strength is improved by preventing stress concentration in the weld toe part. <P>SOLUTION: A welding torch 21 is located in such a manner that a weld zone is welded from the upper part, a pipe member 3 and a flange 5 for fitting set in a welding tool 15 are rotated with the center axis X of the pipe member as the center, and joining is performed over the whole circumference of the pipe member 3 by MAG welding using a gaseous mixture of argon (Ar) and carbon dioxide (CO) as a shielding gas. <P>COPYRIGHT: (C)2008,JPO&INPIT |
