A mobile arrangement for laying a continuous pipeline comprises a resistance welding apparatus, an outer flash trimmer, and at least one pipe-laying means. A jib of the pipe-laying means has a longitudinal support structure suspended therefrom. A suspension is attached to this longitudinal support structure. The front end of said longitudinal support structure carries an outer flash trimmer, and the rear end of said longitudinal support structure carries an inductor for thermal treatment of the weld.

A welding bulge removing apparatus comprises a ring-shaped carrier adapted to be placed by means of rollers on welded pipes at the weld bulge, and being provided with a circumferential guideway and gear rim. It also comprises motor-operated carriages each having a driving gear wheel and support rollers. Mounted on the carriages are milling cutter units movable to and from the weld bulge. The gear wheel and the support rollers are brought respectively into engagement with the gear rim and the circumferential carrier.

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.
