Clamp ring design and manufacturing method

A clamp ring (500;1000) and process for manufacturing a clamp ring (500;1000) to effectively reduce, if not eliminate, waste scrap from the manufacturing process. The clamp ring (500;1000) and process for manufacturing the same, results in clamp ring (500;1000) having a seam (1100) formed by a metal joining technique such as welding, brazing, bolting, soldering, and clinching.
