Abstract (en)
[origin: EP1595610A1] The machine to form a continuously welded metal tube has a feed for the metal strip to a water cooled die chamber (9). The die chamber has a diamond shaping former ring (8) to form the strip into a tube with a longitudinal slot. The slot is closed by a welding head to form a closed tube. An outlet for a shielding gas can be formed between the welder and the former ring.
