Abstract
A weldment includes a first component, a second component, and a weld joint coupling the first and second components together. The weld joint forms a heat affected zone in the first component and creates residual tensile stress in the first component. The first and second components cooperate to define a pocket configured to position a highest magnitude of the residual tensile stress in the first component in a location that is outside of the heat affected zone of the first component.
