ABSTRACT:
A device for the inside scarfing of tubes or profiles longitudinally welded in a tube welding line consists of a tool carrier guided on guide rollers inside the tube to which a cutting ring is attached. The cutting ring is clamped in a cutting ring holder and can be rotated about its central axis which is inclined at an acute angle to the longitudinal axis of the tube. The cutting ring can be retracted from the cut, whereby at the same time as the retraction of the cutting ring, the clamp can be released and the cutting ring can be turned further by a defined angle. The device is controlled by at least one hydraulic or electric line leading out from the welding point of the tube or profile in the tube welding line.
