相位摩擦焊工艺及设备研究

Research on the Process and Equipment of Phase Friction Welding

研究了相位摩擦焊机的检测系统，采用不刹车焊接工艺，确定了最佳定相位时机和定相位机构．在目前通用摩擦焊机上稍加改动即可实现３６０°内任意定相位，成品率高于９９％，定位精度达到了±０．３°．

Using the method of not braking down welding proeess, the phase friction welding testing system has been researched, and the optimal phase time and mechanism has been deter- mined. A little innovation on the general friction welding machine in the country will realize reaching any phase in 360°, and the finished product rate reaches 99% and the phase precision ±0.3°.
