Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a welding technique capable of preventing deflection of a work even if the work is welded on a base and hoisted. SOLUTION: A first positioning member 27 and a second positioning member 29 are provided on a work fixing table 12 via a first cylinder 21 and a second cylinder 22, and these cylinders 21, 22 are controlled by a controller. The controller lowers the first positioning member 27 or the second positioning member 29 that is expected to interfere with a welding robot based on the movement information of the welding robot and the position information of the positioning members 27, 29. When hoisting a car body panel 13 to move it, the car body panel 13 is prevented from being deflected because its rigidity is sufficiently secured. COPYRIGHT: (C)2009,JPO&INPIT
