| Abstract: | Adopted electro-hydraulic proportional valves, a computer closed loop control system of friction welding was developed, in which a closed loop control of the axial pressure during friction welding is accomplished and both the rotational speed of the main shaft and the axial shortening displacement can be measured in real time. The examination of characteristic and quality on production scene shows that the control system has high anti-disturbance and good reliability. It has been applied in the production of drill piper. |
