Abstract: A method is provided that involves a component (20) including a first fastener aperture (36) that extends through the component (20). During the method, the component (20) is machined to enlarge the first fastener aperture (36) to provide an enlarged aperture (54). The component (20) is friction plug welded to plug the enlarged aperture (54) with friction plug welded material (56). A second fastener aperture (36B) is machined in the friction plug welded material (56), where the second fastener aperture (36B) extends through the component (20).
