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.

An apparatus for facilitating a pivotal movement of an implement relative to an arm of a machine includes a link. The link includes a first end segment, a second end segment, and an intermediate segment extending therebetween. Each of the first end segment and the second end segment includes an eyelet portion, and a stub portion that extends integrally and contiguously from the eyelet portion. The intermediate segment is coupled to the stub portion of the first end segment and to the stub portion of the second end segment.

A retention clip used to retain workpieces during welding includes a spacer that extends along an axis and a plurality of first and second spring members positioned on opposite sides of the axis. The first spring members may be spaced apart from each other along the axis and configured to constrain a portion of a first workpiece between the first spring members and the spacer. And, the second spring members may be spaced apart from each other along the axis and configured to constrain a portion of a second workpiece between the second spring members and the spacer.
