ABSTRACT:
Connecting ends on a hose piece comprising several metal layers, in particular a strip wound metal hose piece, are produced by fixing the overlapping metal layers of a hose of larger length or of an endless hose in the region of the point of separation through welding and subsequently cutting off the hose piece from the longer hose or the endless hose. For simple and inexpensive fixing of the metal layers in the region of the point of separation, a welding seam is generated which extends through at least part of the periphery of the hose or about its entire periphery, using roller seam welding. The hose piece can subsequently be separated along the welding seam obtained in this manner, e.g. along its central line, thereby ensuring permanent and reliable fixing of the metal layers in the region of the connecting end.
