  • Structure having stress protected groove weld and structural members forming the same
    Patent number: 11253956
    Abstract: A structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.
    Type: Grant
    Filed: April 3, 2020
    Date of Patent: February 22, 2022
    Assignee: Caterpillar Inc.
