ABSTRACT:
A sucker rod is composed of three initially separate parts comprising a relatively long body member and duplicate relatively short pin members. Upsetting steps are performed on the relatively long body member, whereas only machining steps are employed in making the pin members. One end of each pin member is inertia welded to each end of the body member after the various ends have been cut or ground to provide relatively smooth surfaces.
