ABSTRACT:
A self-propelling bevel fusion-cutting machine for beveling pipes comprises a machine main body which holds a fusion-cutter, such as a burner, for effecting the bevel fusion-cutting of the end face of a pipe, traveling guide rollers which roll on the pipe end face, and outer roller which rolls circumferentially on the outer peripheral surface of the pipe, and an inner roller which rolls circumferentially on the inner peripheral surface of the pipe. The machine main body is movable along the pipe end face by means of these rollers. The outer or inner roller is removably pressed against the peripheral surface of the pipe and this roller or the other roller is connected to a drive source mounted on the machine main body so as to be thereby driven for rotation. The axis of rotation of the rotatably driven roller is inclined along the movement direction of the machine main body, so that with rotation of the driven roller the machine main body is capable of moving circumferentially along the pipe end face while holding the traveling guide roller in intimate contact with the pipe end face.
