传统的无损检测方法具有一定的局限性 ,例如 :在高温高压、高湿、有毒等某些恶劣检测环境中 ,或被测工件具有放射性或腐蚀性 ,以及被测工件具有较快的运动速度时 ,已不能完全满足要求。因此 ,人们一直都在努力寻找适合于上述情况的无损检测方法。这里介绍一种激光超声检测技术 Traditional non-destructive testing methods have some limitations. For example, in some harsh testing environments such as high temperature, high pressure, high humidity and poison, or when the measured workpiece is radioactive or corrosive and the measured workpiece has a fast moving speed , Can not fully meet the requirements. Therefore, people are always trying to find non-destructive testing methods suitable for the above situations. Here is a laser ultrasound detection technology
