, The position adjusting table 20 is moved, the first cylinder device 32 is driven to hold the backing member 2 against the welded portion 1a, and the second cylinder device 40 is driven to grind the backing bead. The tool 41 is rotated by rotating it, and before the Uranami bead is completely cooled, that is, while the grinding resistance is small, the operator automatically grinds the workpiece 1 at any time. There is no need to hold the backing member 2 on the welded portion 1a or grind the backside bead in a state where it has entered the lower narrow place, so that the work for the treatment of the welded portion 1a is facilitated. Welding time can be reduced.

As is apparent from the above description, the present invention provides a guide cart that moves along the work to be welded, attaches a position adjuster to the guide cart, and attaches the position adjuster to the position adjuster via a lifting device. It supports the position detector for detecting the position of the grinding tool and the Uranami bead, and drives the position adjustment device according to the detection signal from the position detector to move the position adjustment table. In addition, there is no need for the operator to grind the Uranami bead while entering the narrow space below the workpiece, and the grinding of the Uranami bead can be performed automatically and easily with a simple device. Therefore, it is possible to reduce the number of grinding operations of the Uranami bead during welding and reduce the number of welding operations.
