  • Device for use with a friction stir spot welding (FSSW) apparatus
    Patent number: 8052028
    Abstract: A device for use with a welding apparatus, such as a friction stir spot welding (FSSW) apparatus, that maintains work pieces in a generally flat or flush orientation during a welding operation. The device can be mounted to the operable end of an FSSW apparatus so that it exerts a stabilizing force against an upper work piece. The stabilizing force exerted by the device prevents the upper work piece from deflecting when the rotating tool of the FSSW apparatus passes through the upper work piece and penetrates into the lower work piece. In an exemplary embodiment, the device includes a housing component that slidably receives a movable component under the force of a biasing component.
