Abstract:
A multi-shouldered friction stir welding tool comprises an exterior threaded solid pin having a diameter and a length; a shoulder having a threadless inner diameter slightly larger than the diameter of the exterior threaded solid pin and at least one substantially radial threaded set screw hole; an monolithic shoulder-shank having a threadless inner diameter slightly larger than the diameter of the exterior threaded solid pin and at least one substantially radial threaded set screw hole; a pair of locking nuts having a threadless outer diameter and a threaded inner diameter operably compatable with the exterior threaded solid pin, wherein the shoulder and the monolithic shoulder-shank are capable of slidable engagement with the exterior threaded solid pin along the length of the exterior threaded solid pin to set a space slightly larger than a thickness of a work piece to be welded.
