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.

Resistance welding apparatus for joining pipes end to end

An apparatus comprises a body having V-shaped two-arm levers mounted thereon. Around the periphery of the body there are mounted cutting tool holders pivoted each to one arm of each of the levers. Secured to the body are drives for turning the levers and each connected with the other arm of each of the levers. On the front and rear ends of the cutting tool holders there are mounted rollers in contact with the inside surface of the pipe. Rigidly attached to the cutting tool holders are cutting tools.

Apparatus for removing flash from pipes

Work pieces to be joined together by the flash butt welding method are brought together at a preset no-load voltage, the end faces of the work pieces are fused, and an upsetting is accomplished. The amount of the upsetting is determined within from 1.2 to 3.0 of the amount of the maximum gap between the end faces of the work pieces being welded together, which gap forms in the course of fusing the end faces of the work pieces. The maximum gap is determined from the following relation:

Method of flash butt welding

A device for removing flash from rails after resistance butt welding, mounted on a welding machine case and split along the vertical axis of the rail, comprising three cutters embracing the rail along the entire cross-sectional perimeter thereof and coupled with a hydraulic cylinder drive, one of said cutters is pivotally mounted on said case, split along the vertical axis thereof and contacts the rail rolling surface, while the two side cutters which embrace the sides of the rail head, the web and the base flange of the rail are arranged symmetrically relative to the vertical axis of the case and hinged thereto, the top portions of said side cutters being linked by an articulated rod.
