  • Patent number: 10338032
    Abstract: An assembly includes a sensor configured to obtain a data scan of a joint. A controller is operatively connected to the sensor. The controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for automated quality assessment of the joint. Execution of the instructions by the processor causes the controller to: obtain the data scan of the joint (via the sensor) and generate a first image based on the data scan. The first image is divided into a plurality of pixels having respective numeric values. The controller is programmed to identify a region of interest as the plurality of pixels from the first image with a respective numeric value greater than a threshold value (I0). The controller is programmed to assess joint quality based on a porosity factor (PF) determined at least partially from the data scan.

  • Publication number: 20180056578
    Abstract: An ultrasonic tooling system for texturing a workpiece includes a horn having an end portion forming an interface with the surface of the workpiece. The end portion of the horn has a texture formed thereon. As a result of a high frequency ultrasonic vibration, the surface of the workpiece takes on a mirror image of the texture of the end portion of the horn. Alternately, the texture may be formed on an anvil and wherein, as a result of a lower frequency ultrasonic vibration, the surface of the workpiece corresponding to the anvil takes on a mirror image of the texture of the upper surface of the anvil.

  • Patent number: 9878489
    Abstract: Friction-weld assemblies and methods of spin-welding are provided, where the components being joined are polymeric components. Designs provided for the polymeric components enable the use of relatively low speeds and pressures to achieve superior friction weld joints between the components. Further, large surface area polymeric components can be successfully friction welded with such designs. In certain variations, at least one polymeric component has a weld surface with a plurality of surface features that are concave (e.g., grooves) or convex. In other variations, the first component in the weld region has a distinct non-complementary shape from the second component, thus creating a progressive advancing weld line that avoids high temperatures that might incur damage to the polymeric component and weld joint. Such component designs additionally provide for improved flash management at the weld joint.

  • Patent number: 9808856
    Abstract: The present disclosure relates a rivet body, including a rivet head and a rivet shank, composed of a different material than a mandrel used for insertion into a workpiece(s), the mandrel including a mandrel shaft and a mandrel cap. The rivet body receives the mandrel shaft, including the mandrel cap, through the rivet shank. The mandrel shaft is received by the installation tool, which rotates the rivet body, and the mandrel cap locally deforms workpieces(s) through friction riveting to install the rivet body. During the friction riveting, the fast-rotating rivet body is pushed into the workpiece(s) causing local deformation/melting where the mandrel cap contacts the workpiece(s). The mandrel cap creates a cavity which progresses through an upper surface and a lower surface of the workpiece(s).
