Abstract
PURPOSE: To enable a backing strip be mounted readily from the front side face of the groove of welding base metals by penetrating the backing strip from the front side to the back side of the groove of the base metals and rotating the same with respect to the support members connected by rotatable joints until it contacts the back side of the groove.
CONSTITUTION: A backing strip 3 is penetrated from the front side A of the groove 2 of welding base materials 1, 1 to the back side B through the root gap 2a of the groove 2. The support members 4 provided with screw parts 5 are beforehand mounted to both ends 3a, 3b of the backing strip by means of rotatable joints 4a. When the backing strip 3 fully penetrates to the back side B of the groove 2, it is rotated by the joints 4a until it contacts the back side face 1b of the groove 2, thence keep plates 6 are passed to the support members 4 and are locked up by nuts 7 to closely fit the backing strip 3 to the back surface 1b of the groove 2. After the backing strip 3 and welding base metals 1 are tack-welded, the nuts 7 and keep plates 6 are removed and the support members 4 are gas-cut, thence the backing strip 3 is surely mounted to the groove back surface 1b. The backing strip which is difficult to be directly mounted from the back side is made readily mountable from the front side.
