  • Tapered friction stir welding and processing tool
    Publication number: 20070057015
    Abstract: A friction stir welding tool is provided for joining together workpieces utilizing friction stir welding processes having convex- or concave-shaped tapered shoulders. The inventive tool includes a support body rotatable about a first axis and having a distal end defining a shoulder. A rotatable pin extends from the distal end of the support body downward and away from the shoulder. The shoulder of the support body includes at least one section that is tapered, with the taper extending downward toward the pin. In a second embodiment, the pin of the tool has been removed to provide a friction stir surface processing function, and includes tools having either straight, convex-shaped or concave-shaped tapered shoulders.
