  • Laser welded assembly having a heat affected zone reinforcement and method of making the same
    Patent number: 11701738
    Abstract: A laser welded assembly and method of making. The laser welded assembly includes a first work piece having a thickness (T1) defined between an external surface and a faying surface; a second work piece having a thickness (T2) defined between an external surface and a faying surface of the second work piece; a weld seam having a core fusion zone extending from the external surface of the first work piece through the faying interface and at least partially into the thickness (T2) of the second work piece; and a protruding fusion zone extending laterally from the core fusion zone adjacent to the external surface of the first work piece. The protruding fusion zone may be formed by post-heating or concurrently with the core fusion zone.

  • HEALING ENERGY BEAM FOR SMOOTHENING SURFACE IRREGULARITIES IN WELD JOINTS
    Publication number: 20220388096
    Abstract: A method for healing surface irregularities in a weld joint includes generating a healing energy beam by a focused energy device, where the healing energy beam includes a predefined energy density. The method also includes scanning the healing energy beam along at least a portion of a periphery of the weld joint, where the weld joint includes at least an upper layer and a lower layer. The method also includes melting less than half a thickness of the upper layer of the weld joint. The predefined energy density of the healing energy beam is based on the thickness of the upper layer of the weld joint.
