  • Refill friction stir spot welding tool and end effector
    Patent number: 11458563
    Abstract: A quick connect refill friction stir spot welding tool includes a clamp having a first radially-projecting mounting tab configured for engaging a first mounting slot in a refill friction stir spot welding weld head. A friction sleeve is located coaxially within the clamp and has a second radially-projecting mounting tab configured for engaging a second mounting slot in the refill friction stir spot welding weld head. The second radially-projecting mounting tab is located higher along an axis of the tool than the first radially-projecting mounting tab, and radially inward thereof. A friction pin is located coaxially within the clamp and friction sleeve. The clamp and friction sleeve are attachable to and detachable from the refill friction stir spot welding weld head by rotations through less than 360 degrees.
