| Abstract: | For controlling the quality of friction welding process, a computerized closed-loop control system with electro-hydraulic proportional valves is set up. The axial pressure during friction welding can be controlled in closed-loop. The moving speed of slipway can be proportionally controlled. The rotating speed, axial pressure, friction torque, as well as interface temperature, can be examined in real time. The statistical analysis of production data using the control system shows that the average error of axial pressure during friction welding is lower than 2%, and the error variance factor is close to zero. The stability of the friction welding parameters is improved greatly. |
