Abstract
PURPOSE:To adjust the height of a backbar quickly and correctly by provisionally fixing a backbar by adjusting the position so that the tip face becomes more than a reference height, pressing the tip of an adjusting rod to said tip face and pushing down to the reference height. CONSTITUTION:A work is welded between the numerous backbars 5 erected on a jig 1 and the electrode(not shown in figure) loaded on the welding gun 4 of a welding robot. In this spot welding, the reference height H of the tip face 6 of the backbar 5 is stored in said welding robot in advance. At the time when the tip face 6 of the backbar 5 is worn and broken with the repeated welding it is reproduced by grinding. The back bar 5 is then fixed provisionally with its positional adjustment so that said tip face 6 becomes more than the reference height H at least. Thereafter the tip 13a of an adjusting rod 13 fitted by changing to the electrode of the welding gun 4 is pressed to said tip face 6. The backbar 5 is then pressed down to said reference height H based on said stored value. This backbar 5 is thereafter fixed to re-open the spot welding work.
