摘　　要：针对油气管道破裂维修过程中形成的B型套筒搭接焊缝尚缺少有效的超声无损检测技术及设备的问题,文章提出了一种新的搭接焊缝超声检测方法,并开发了相应的超声B扫描检测系统,从检测方法、检测系统的组成和工作原理、检测系统功能的验证实验等方面进行了论述。模拟实验结果表明,该系统可有效检测出试样上的预埋缺陷,具有良好的探伤效果及应用前景。In order to solve the problem that there are not effective NDT technique and instrument to detect the lap weld formed by using B type sleeve to repaired the long distance oil and gas pipeline, the method using multi probes is proposed, and B-scan ultrasonic inspection system is developed. The inspection method, system configuration, working principle and experimental verification of function are discussed in the paper. The simulation experiments show that the artificial defects made on the sample pipe can be detected effectively, the system has good inspection capability and application prospect.
