  • Dynamic calibration assembly for a friction stir welding machine
    Patent number: 8079276
    Abstract: A calibration assembly for a friction stir welding machine having a rotatable pin tool with upper and lower shoulders. The calibration assembly includes: a force measuring component for placement between the upper and lower shoulders of the pin tool; an upper bearing for placement between the upper shoulder of the pin tool and the force measuring component for permitting relative rotation therebetween; and a lower bearing for placement between the lower shoulder of the pin tool and the force measuring component for permitting relative rotation therebetween. The upper and lower bearings permit the pin tool to be rotated relative to the force measuring component during a calibration procedure. This permits the force measuring component to measure the forces directly applied by the pin tool while the upper and lower shoulders are either stationary or rotated relative to the force measuring component.
