ABSTRACT:
A friction stir weld apparatus having a linear drive actuator and a separate friction stir weld device. The linear actuator and the friction stir weld device are driven by concentric motors. In the preferred embodiment, the thrust member of the actuator is connected to the friction stir weld device within or adjacent to the friction stir weld device motor to advance and retract the friction stir weld device along a linear axis concentric with the actuator and friction stir weld device motors.
