| Abstract: | The small diameter pipes butt welds with natural defects such as crack, lack of fusion, lack of penetration and so on were inspected by both phased array（PA） ultrasonic inspection technology and radiographic testing technology. The results with up two inspection technologies were compared and analyzed. The advantage, and application prospects of PA technology in the field of inspecting small diameter pipes were overviewed. |
