摘要： In a process for producing longitudinally welded tubes, a metal strip, which is continuously pulled from a supply, is gradually formed into a slit tube and the longitudinal slit of said slit tube is welded. The metal strip (2) is pulled through a plurality of drawing dies (8, 9, 10, 11) arranged one behind the other and having a diameter that decreases in production direction, and in each of the drawing dies (8, 9, 10, 11) is increasingly bent in circumferential direction. The slit tube is closed in a last forming step (15) immediately in front of the welding point.
