焊缝用超声波探伤比 X 射线探伤有许多优点,特别是在条件较差的工地现场,采用只有五公斤重的 CTS—8型超声波探伤仪,比起笨重的 X 射线机来,既方便灵活,又可对焊缝作较全面的检查。又因对人体无害,探伤速度快,探伤与焊接可同时进行作业,所以深受探伤工作者与焊工的欢迎。但是,往往不同的探伤人员采用的方法各不相同。我厂试用过几种方法,在实践中 Weld ultrasonic flaw detection than X-ray flaw detection has many advantages, especially in the poor site conditions, using only five kilograms of CTS-8 ultrasonic flaw detector, compared to cumbersome X-ray machine, convenient and flexible, But also for a more comprehensive inspection of the weld. Because of the harmless to the human body, testing speed, testing and welding can be carried out at the same time, so welcomed by the testing workers and welders. However, different types of inspectors often use different methods. I tried several methods factory, in practice
