Abstract
A multi-axis articulatable robot with a weld gun having a pair of opposing arms, where at least one arm is movable relative to the other arm to apply pressure to a workpiece during a welding operation. At least one of the opposing arms of the weld gun can be rotatable or translatable relative to the other arm. At least one arm is moved relative to the other arm by an inverted roller screw linear actuator. The robot can include an electric controller for controlling the operation of the actuator of the weld gun as an additional axis of the robot movement. The actuator can be mounted on either of the opposing arms.
