Abstract:
Pin tool assemblies for friction stir welding and apparatus and methods that include the pin tool assemblies. The pin tool assemblies include an outer member, an inner member, and a stop. The outer member includes an inner surface that defines an elongate internal cavity and an external shoulder that includes an opening to the elongate internal cavity. The inner member includes a welding end, extends at least partially within the elongate internal cavity, and projects from the opening such that the welding end is external the elongate internal cavity. The pin tool assembly is configured to permit motion of the inner member relative to the outer member. The stop defines a plurality of stop configurations. Each of the stop configurations restricts motion of the inner member relative to the outer member in a stop direction to define a corresponding stop distance between the welding end and the external shoulder.

Claim (Index 1):
A method of operating a friction stir welding apparatus (FSWA), the method comprising:\n locating a workpiece on an anvil of the FSWA, wherein the workpiece includes a joint between two bodies to be friction stir welded together; rotating a pin tool assembly of the FSWA; plunging a welding end of an inner member of the pin tool assembly into the workpiece; maintaining an external shoulder of an outer member of the pin tool assembly in contact with an anvil-opposed surface of the workpiece, wherein the outer member defines an elongate internal cavity, and further wherein the inner member extends through the elongate internal cavity; translating the welding end of the pin tool assembly along the joint to friction stir weld the two bodies together; and during the translating, restricting motion of the welding end relative to the external shoulder in a stop direction with a stop, wherein the stop defines a plurality of stop configurations, and further wherein the restricting includes restricting within the elongate internal cavity.
