治具。 A jig used when welding a flange pipe joint to a pipe body, which includes a pipe fixing blade having sloped surfaces at the bottom of both ends, a fixed core and a movable core having support surfaces corresponding to the sloped surfaces of the blade. and a support shaft that holds these two cores, the fixed core is fixed to the tip side of the support shaft next to the ring for pipe sealing, and the movable core has a flange at the rear and is attached to the support shaft in the axial direction. The blade is movably supported and held between a fixed core and a moving core at a predetermined interval so as to be able to move in and out according to the movement of the moving core in the axial direction;
In addition, a handle is provided adjacent to the collar of the moving core to be screwed into the support shaft, and an inert gas supply hole is drilled from the rear end of the support shaft between the fixed core and the moving core. Features: A jig for welding flange pipe joints.
