Elaborated in the essay are the domestically employed two manufacturing methods for the G.D hollow sucker rod,which respectively take friction welding and hot-forging as key techniques. Based on standard SY/T 5550—2012,a contrastive analysis is conducted in respect of the G.D directly-connected hollow sucker rod made with the friction welding process, and that made with the upsetting process in terms of process routing, manufacture difficulty,product performance,and actual application result. The analysis result shows that compared with the G.D directly-connected hollow sucker rod as made with the friction welding process, the G.D directly-connected hollow sucker rod as made with the upsetting process features such advantages as fewer manufacturing steps, easier realization of automatic production,higher stability of all the product properties,and better operation effectiveness.
