Title: METHOD FOR PRODUCING A WELDED RING
Abstract:
For producing a welded ring, a strip of a length corresponding to the circumference of the ring is bent into a ring and is welded at its ends. The ends of the strip that are to be welded to one another have in the circumferential direction of the ring an offset that lies in the plane of the strip. The welding is performed from both side edges of the ring, from the outside to the inside, as far as the offset. This avoids an overlapping welding in the middle of the strip of a welding quality that differs from the edges.
