Abstract
A method for manufacturing a coaxial cable is described, whereby a dielectric layer (2) is extruded over an inner conductor (1), a lengthwise incoming metal strip (3) is formed into a tube, having a lengthwise slot around the insulated conductor (1, 2). The tube (3) is welded along the slot to thereby form a welded seam (4), and the welded tube is drawn down onto the surface of the dielectric layer (2). A metal strip (3a) having a plastic coating (3b) at least on one of its major surfaces is used to form the tube (3), and its lengthwise edges are welded by a laser (19).
