SYSTEM AND METHOD FOR HOLDING MATERIALS HAVING ARCUATE SURFACES IN PLACE FOR FRICTION STIR WELDING OR PROCESSING

摘要

A system and method for holding a friction stir processing material in place on a substrate having a curved surface for the purpose of mixing the friction stir processing material into the curved substrate using a solid-state process, wherein the system includes selecting one of a variety of mechanical means of attaching the friction stir processing material to the substrate that will enable friction stir processing to be performed that is economical, efficient and safe.
