Claim 0:
1. A method of producing a welded multi-crimp ring, the method comprising:
bending a band of a length corresponding to a circumference of the ring to form the multi-crimp ring, wherein a V-Shaped offset lies in a flat plane of the band prior to the bending, and the bending of the band changes the band to a cylindrical ring with a circumferential surface, wherein the flat plane of the band becomes a curved plane; and
welding the curved plane of the band at its ends from both lateral edges of the multi-crimp ring from the outside inwards,
wherein band ends to be welded together have a V-shaped offset in the circumferential direction of the welded multi-crimp ring,
wherein the V-Shaped offset lies in the circumferential surface of the welded multi-crimp ring, and
wherein the welding is performed in a continuous straight line such that a resulting weld seam fully covers the V-shaped offset.
