Abstract:
A radiused corner support plate is used to form a corner void when making L- and T-corner welds that are filled with plasticized work piece material during friction stir welding to form a filleted corner weld. An improved friction stir welding tool uses either disrupting features such as crossed rectangular grooves in the distal tip end or a curved tip region or both to improve plasticized work piece material flow below the distal end and in the region of the fillet.
