Claims

[Scope of utility model registration request]

For a pipe 1 with openings at both ends into which the ends of two reinforcing bars 5, 5 to be joined by welding fit, a through hole 2 for welding is provided at only one location approximately in the center of the cylindrical wall of the pipe. In the welded joint pipe, a stopper 3 having a width approximately equal to the groove gap between reinforcing bars is protruded from the inner surface of the pipe at approximately the center of the pipe 1, corresponding to the opening of the through hole 2. A pipe for a welded joint in which clamp bolts 8, 8 are threaded through the cylindrical wall of the pipe with a stopper 3 in between.
