Abstract

Pipes with spiral or longitudinal seams are welded first by arc tack welding during rolling and then final arc welding. Tack welding is effected by moving the welding head to and fro over the edges of the blank to be joined. During movement of the welding head in the direction of blank advancement, which is effected at a speed equal to the difference between the speed of blank advancement and the welding speed, the edges are arc welded.
