A tool for forming a friction stir weld, the tool comprising:
- a support body having:
- a longitudinal axis,
- an outer surface centered on the axis, and
- a distal end having a distal face centered on the axis and extending to a distal face perimeter,
- a pin extending from the distal face along the axis,
- a scroll pattern in the distal face, the scroll pattern comprising multiple arcuate grooves in the distal face, each groove extending from a groove start location located between the axis and the distal face perimeter, to a groove end segment at the distal face perimeter, and
- chamfered shoulder segments at the distal face perimeter between the groove end segments.
