  • Distortion prediction and minimisation in additive manufacturing
    Patent number: 10525630
    Abstract: A method of minimising distortion in a workpiece is described that includes utilizing a computer system to carry out finite element analysis on a finite element thermo-mechanical model of the workpiece during and after fabrication by additive manufacturing to predict shape distortion and residual stress development in the workpiece, wherein the fabrication includes the fabrication step of depositing multiple layers of a material melted by a heat source along a deposit path on a substrate, and introducing alterations to the workpiece prior to or during fabrication to compensate for the predicted distortion.
    Type: Grant
    Filed: March 9, 2018
    Date of Patent: January 7, 2020
    Assignees: The Boeing Company, Commonwealth Scientific and Industrial Research Organisation

  • Apparatus for friction stir welding
    Patent number: 9289849
    Abstract: One aspect of the disclosure relates to a friction stir welding apparatus. The friction stir welding apparatus includes a spindle housing and a pin tool concentric with an axis and rotatable relative to the spindle housing about the axis. The friction stir welding apparatus also includes a first shoulder not substantially rotatable relative to the spindle housing about the axis and a second shoulder not substantially rotatable relative to the spindle housing about the axis. The pin tool is rotatable relative to the first shoulder and the second shoulder.
