ABSTRACT:
The present invention provides a friction stir welding device for optimizing the depth of a friction stir welding tool in a workpiece. The welding device includes a spindle and a welding tool in rotatable communication with the spindle. The welding device also includes an inner housing defining an aperture through which the welding tool at least partially extends. Preferably, the inner housing has a plurality of cam followers. The device also includes an outer housing defining an aperture for at least partially receiving the inner housing. The outer housing has a base member and a riser that is rotatably mounted to the base member and that defines a plurality of inclined surfaces upon which the plurality of cam followers ride. The welding device includes a sensor in electrical communication with a controller for measuring the magnitude of force exerted by the welding tool upon the workpiece. In one embodiment, the welding device includes a motor and belt drive assembly responsive to the controller and in operable communication with the riser to modify the depth at which the welding tool is inserted into the workpiece and, correspondingly, the force exerted by the welding tool upon the workpiece.
