Retention component

Method of manufacturing first structural component for or joining with second structural component by groove weld is provided. The first structural component has first surface, second surface and end portion. The component is bent at end portion to form bent portion defining convex and concave faces. First portion of bent portion is removed at convex face in form outer weld surface having first face extending from first surface, and second face connected to first face. Second portion of bent portion is removed at concave face to form inner edge surface having arcuate profile. Inner edge surface extends from second surface and connects to second face via transition portion. A portion of first face, second face, transition portion, and inner edge surface define root protrusion, having a root protrusion height, for first structural component. The root protrusion defines stress protected weld root region isolated beyond and away from root stress flow path.
