PURPOSE:To provide the titled device which improves working efficiency without dividely providing set stations by alternately throwing the works set on respective set jigs from the respective set positions provided at specified angle differences to the set station to a front welding station by the swiveling action of a swiveling frame. CONSTITUTION:The work C is set in one set position 211 onto the jig 5 shown by X of two units of the set jigs 5, 5 imposed on respective arms 12 of the swiveling frame 13 and thereafter, the frame 13 is turned 120 deg. clockwise from the state shown by a solid line. The X jig 5 is thereby moved forward from the position 211 to a tack welding station 2, by which the work C is thrown to the station 2 and the jig 5 shown by Y is moved backward to the other set position 212 the next work C on the Y jig 5 is then set in the position 212 during tack welding of the work C in the station 2. A tack welded rear frame B is transferred onto the 1st hanger carriage 81 upon ending of tack welding and is conveyed, then the frame 13 is turned 120 deg. counterclockwise and thereafter the work C is continuously welded.
