Apparatus for removing a welding bulge from resistance welded pipes

A welding bulge removing apparatus comprises a U-shaped carrier adapted to be placed by means of rollers on welded pipes at the weld bulge, and being provided with an arcuate guideway and a toothed segment. It also comprises a motor-operated carriage having a driving gear wheel and support rollers. Mounted on the carrier are cutting tool holders movable to and from the weld bulge. The gear wheel and the support rollers of the carriage are respectively brought into engagement with the toothed segment and the arcuate guide-way of the carrier. The carriage is adapted to be rigidly connected to a lifting mechanism of a vehicle used for raising and carrying the welding bulge removing apparatus, whereby rotation of the carrier is effected, while the carriage remains immobilized.
