摘要： A device for corrugating a metal pipe having a corrugation extending transversely of its longitudinal direction. The device has a ring-shaped corrugating head drivable by a first electric motor and is rotatable about its axis in the operating position and a ring-shaped corrugation disc, coupled to the ring-shaped corrugating head, projects radially inwardly from the corrugation head. The corrugation disc is mounted in the corrugation head so as to be adjustable in the radial direction. A support, coupled to the corrugation head, is arranged so as to also be rotatable about the axis of the corrugation head. An adjusting mechanism acting on the corrugation disc is mounted on the corrugation head. The adjusting mechanism serves for radially adjusting the corrugation disc and is adjustable by the support. The support is connected to a second electric motor serving for rotating the support about the axis (A) of the corrugation head.

摘要： A device for undulating a metal pipe having an undulation extending transversely of its longitudinal direction. The device has a ring-shaped undulating head drivable by a first electric motor and is rotatable about its axis in the operating position and a ring-shaped undulation disc, coupled to the ring-shaped undulating head, projects radially inwardly from the undulation head. The undulation disc is mounted in the undulation head so as to be adjustable in the radial direction. A support, coupled to the undulation head, is arranged so as to also be rotatable about the axis of the undulation head. An adjusting mechanism acting on the undulation disc is mounted on the undulation head. The adjusting mechanism serves for radially adjusting the undulation disc and is adjustable by the support. The support is connected to a second electric motor serving for rotating the support about the axis (A) of the undulation head.

摘要： A device for continuously manufacturing pipes of metal, wherein the device includes a shaping unit (4) for shaping a pipe with a slot extending in the longitudinal direction from a longitudinally arriving metal strip, a welding device (7) for welding the contacting edges of the metal strip at the slot of the pipe, and a pulling device for pulling the pipe (9) which is now circumferentially closed in its longitudinal direction. The welding device (7) is composed of at least two separate welding heads (12,13) arranged in the pulling direction of the pipe (9) at a distance from each other, wherein the welding heads (12,13) each have at least one non-burning electrode.
