ABSTRACT:
A tool for forming a friction stir weld joint in a workpiece is provided. According to one embodiment, the tool includes a rotatable pin having first and second ends and defining a stirring portion therebetween structured to frictionally engage the workpiece so as to at least partially form the friction stir weld joint. In particular, the stirring portion of the pin defines at least one groove and ridge, each of which extend generally circumferentially around an axis of the pin. The tool can also include a second shoulder opposing the first shoulder such that the pin extends therebetween.
