| 摘 要： | 0 IntroductionThe flowleading pipe in pusher of shipping diesel en-gine is constructed by butt welding of 1Cr18Ni9Ti auste-nitic stainless steel circumferential strip with low carbonsteel circumferential strip. It is easy to form stress cracks,slag inclusions, and blowholes etc inside the weldedseam. Thus after turning for the weldment it is necessaryto perform nondestructive test for the welded joint.The weldment is very large in dimension and it is adouble deck construction with vertical a…

| Abstract: | Tthe practical application of ultrasonic wave inspection in welded joint by austenitic stainless steel with carbon steel is presented. It is shown from the experimental results that the high frequency narrow-pulsed longitudinal ultrasonic wave inspection technique can detect the defects in deferent sound path and location within the tested welded joint clearly and exactly. The study in the paper may provide a new approach for further application of ultrasonic inspection in coarse-grained materials. |
