초록 ▼

A method of performing friction stir welding is provided herein. More specifically, traditional friction stir welding requires a rotatable head that is forced against a plurality of work pieces to bond the same. The rotational and normal forces generated by the friction stir welding tool are generally reacted by a backing plate, anvil, mandrel or other mechanisms, such hardware are subject to the applied forces and are often supported with additional internal supports. Conversely, a method of performing a friction stir weld is described that omits the need for such a backing member and internal supports as it is performed using a self reacting pin tool.

대표청구항 ▼

What is claimed is: 1. A method for performing circumferential stir welding without an internal mandrel or any other hardware for providing internal support to pieces being welded, comprising:providing a first ring assembly, comprising:(i) an inner ring interconnected to an outer ring by way of a center ring;(ii) a plurality of clamp assemblies interconnected to a first surface of said center ring; and(iii) a plurality of plates interconnected to a second surface of said center ring providing a second ring assembly, comprising:(iv) an inner ring interconnected to an outer ring by way of a center ring;(v) a plurality of clamp assemblies interconnected to a first surface of said center ring; and(vi) a plurality of plates interconnected to a second surface of said center ring;providing a first plate having an arcuate outer surface and a first end;providing a second plate having an arcuate outer surface and a second end;aligning said outer surface of said first plate and said second plate such that said first end and said second end are abutted to form a seam;positioning said first ring assembly adjacent to said first end;positioning said second ring assembly adjacent to said second end, wherein said first ring assembly is spaced from said second ring assembly with said seam therebetween and wherein said inner surface of said first ring assembly and said second ring assembly are unsupported in a normal direction;creating a bore in said first plate and said second plate wherein a portion of said bore is intersected by said seam;placing a pin of a rotating tool within said bore;forcing said tool onto said first plate and said second plate wherein said force is reacted only by at least one of said first ring assembly and said second ring assembly;rotating said tool;translating said tool with respect to said first plate and said second plate to form a weld therebetween;removing said pin from said seam to reveal a hole; andplugging the hole.
