  • Friction stir welding devices and methods for tandem tool and anvil
    Patent number: 9457423
    Abstract: Friction Stir Welding (FSW) devices and methods for simultaneously welding both sides of an arcuate joint are described. The FSW method includes the step of operating a FSW tool and an anvil on the exterior surface of the joint and simultaneously operating another FSW tool and anvil on the interior surface of the joint. The anvils are positioned in a juxtaposing manner to the FSW tools, and move in tandem with the FSW tools, thus providing a supporting force to the FSW tools during their operation.
    Type: Grant

  • Friction stir welding using a sacrificial anvil
    Patent number: 8827139
    Abstract: Devices and methods for friction stir welding using an anvil with a sacrificial material are disclosed. The method involves the steps of providing an anvil with a sacrificial material on the backside of the workpieces and operating a friction stir welding device to form a weld that joins the workpieces together with the sacrificial material. The anvil comprises a non-sacrificial base portion removably coupled with a sacrificial material.
