摘　　要：根据钢管超声探伤系统对于超声探头实时随动控制的实际功能要求和现场安装情况,采用编码器和到位开关,通过程序控制,实现了钢管超声探伤系统探头相对于钢管运动的随动控制功能,减小了钢管超声探伤系统探测盲区,保证了钢管超声探伤系统的探伤精度和提高了探伤效率。According to the steel pipe ultrasonic inspection system for ultrasound probe with a real-time control of the actual functional requirements and site installation, the encoder and the place switch are adopted. Through program control, it realizes steel pipe ultrasonic flaw detection system for steel pipe movement of the probe relative to the tracking servo control function, decreases the steel pipe ultrasonic inspection system＇s detection blind zone, ensures the accuracy of testing steel pipe ultrasonic flaw detection system and improves the inspection efficiency.
