超声波探测焊缝是一项较新的技术,由于它具有灵敏度高、准确度好、速度快、对人体无害等一系列优点,许多单位都在推广应用。我厂船体焊缝的探伤,以往是采用 X 射线摄片法进行的。由于近年来产量不断上升,工作量不断增加,X 射线探伤已不能满足生产的 Ultrasonic detection of weld is a relatively new technology, because of its high sensitivity, accuracy, speed, harmless to the human body and a series of advantages, many units are in the promotion and application. Our factory hull weld inspection, the past is the use of X-ray radiography method. Due to the rising output in recent years, increasing workload, X-ray inspection can not meet the production
