摘　　要：文章讨论了采用超声爬波检测奥氏体异种钢小径管焊缝,根据爬波的原理设计了奥氏体异种钢小径管焊缝超声爬波探头和对比试块,对检测灵教度和缺陷回波波形进行了分析探讨。The paper discussed about using ultrasonic creeping wave to detect the welding joint of dissimilar austenitic stainless steel small-diameter pipe.Based on the principle of ultrasonic creeping wave, the ultrasonic creeping wave probes used on the welding joint and contrast test block are designed. The detection sensitivity and echo waveform from flaws are also discussed.
