Abstract

The invention falls within the sector of frustoconical pipes. The pipe (1) to be formed and welded is fed between calibrating rollers (8) at a speed greater than the tangential speed of said calibrating rollers (8) in the zone of tangency with the pipe (1). The central axis of the pipe (1) is kept at a constant level during feeding of the pipe, while the height at which welding is performed varies. The extension of the active profile of the calibrating rollers (8) is less than the length of the pipe (1) to be formed and welded.
