Hollow curved structures formed with friction stir welding ; Method of manufacturing such structures

摘要

The present application describes a hollow structure, and a method of forming the hollow structure, where the hollow structure includes first and second metal parts (800), the second metal part (800) having an interior surface and a tapered support member (20) extending from the interior surface. The hollow structure also includes a friction stir welded joint that extends through the first metal part and into the tapered support member to form a curved rib having a curved friction stir weld path (802).
