Based on the analysis of inspection conditions of penetration welds in domestic Nuclear Power Plant,the incompatibility of the pipeline inspection equipment in China and other countries is illustrated.This paper proposes a technical solution for full-penetration circumferential butt weld using the automatic ultrasonic inspection system,with simple and efficient operation,which can realizes rapid installation and positioning of the inspection device in the narrow space.The inspection system is applied to the in-service inspection of penetration pipe welds in Nuclear Power Plant,results show that the inspection system meets the requirements of in-service inspection,and the effectiveness of the technical development is verified.
