| Abstract: | The primary hydraulic system of a friction welding machine was reconstructed by using the proportional relief valve and the new 8 - bit microcontroller P89CS1RD2 of PHILIPS company. The pressure is controlled in closed loop for this system, which guarantees the stability of pressure parameter in friction welding, and makes it easy to adjust the pressure. The practical production shows that the system runs well. |
