Abstract: A method for producing longitudinally welded helically corrugated metal tubing, wherein a metal strip pulled from a strip supply is formed into tubing with a longitudinal slit, the longitudinal slit is sealed by welding and the corrugation is produced by a corrugation tool that is supported eccentrically and at an angle to the tubing axis, is freely rotatable in a rotationally driven corrugator head, and rolls off the surface of the tubing. The metal strip as well as the uncorrugated metal tubing are advanced by a feed device that is provided between the welding point and the corrugation unit. A second feed device (8) engages the corrugated tubing (7) directly behind the corrugation unit (6), and the feed rate of the second feed device is slower than the forward feed rate of the corrugated tubing (7) which results from the pitch of the corrugator disk and the rotational speed of the corrugator head.

Abstract: A method for producing an optical cable with a metal tube and at least one optical fiber arranged in the metal tube, wherein optical fiber(s) are inserted into a slotted tube, the longitudinal slot in the slotted tube is welded, and the diameter of the welded tube is reduced. After the reducing operation, the welded tube is gripped by a draw-off device and conveyed in the finishing direction and wound up onto a draw-off disk. Between the draw-off device (10) and the draw-off disk (11), a force which causes elastic elongation of the metal tube (13) in the finishing direction is applied by the draw-off disk (11), and the extent of the elastic elongation is regulated through this force.

Abstract: In a process for producing a welded joint between the ends of two metal strips in which the butted ends are connected by means of a TIG welder that can be moved perpendicularly to the longitudinal direction of the metal strips, one sheet metal piece each is placed in the area of the butt joint along the longitudinal sides of the metal strips. The two sheet metal pieces are tack-welded to the longitudinal edges of the metal strips in the joint area by means of a spot weld of the TIG welding unit. The strip ends are welded together by moving the welder along the joint edges. The welder is activated on one of the sheet metal pieces and moved up to the opposite sheet metal piece, and the two sheet metal pieces are removed from the longitudinal sides.
