介绍了锅炉大径管对接焊缝超声波探伤根部的反射特点,对缺陷波和内坡回反射波进行了分析,提出了缺陷波和内坡回反射波的识别方法
The reflection characteristic of the root of ultrasonic flaw detection of the large diameter pipe butt weld of the boiler was introduced. The back reflection wave of the flaw wave and the inner slope was analyzed. The identification method of the flaw wave and the backwave reflected from the inner slope
