摘　　要：分析特种设备制造行业无损检测现状,存在的问题;制作典型人工焊接缺陷,包括裂纹、未熔合、未焊透及条状夹渣等缺陷。对试件进行100%射线检测,确定缺陷性质、大小和位置;用K2.0超声波探头在筒体侧进行检测;用不同K值的探头(K1.5、K2.0和K2.5)在封头侧分别进行检测。对两种缺陷评定方式的结果进行对比分析,确定超声波探伤应采取的方案。The status and problems of nondestructive testing of special equipment manufacturing industry are analyzed in this paper.Typical artificial welding defects including cracks,incomplete fusion,incomplete penetration and stripe slag inclusion are made.100% radiographic testing is done to the specimen to determine the nature,size and position of the defect.The K2.0 ultrasonic probe is used to test the cylinder side;different K value probes（K1.5、K2.0 and K2.5）are used to test the head side respectively.The results of two kinds of defect assessment methods are analyzed to determine the solution that should be taken in ultrasonic flaw detection.
