摘　　要：提出了利用小角度纵波探头和横波探头相结合对汽包中径管管座角焊缝进行超声波探伤的方法 ,对小角度纵波探头进行了设计 ,对两种探头的标准反射体与判伤标准进行了统一。实践证明 。An ultrasonic flaw detecting method using small angle longitudinal and associated with transversal wave probes for fillet weld of medium-sized tube seat in boiler steam drum is proposed by the authors.They design the small angle longitudinal wave probe and set a standard reflecting blocks of both probes and common flaw-detection criteria.Practice shows that this method can effectively solve the flaw detecting problems of fillet weld of medium-sized tube seat in steam drum.
