无损检测是包含若干常用技术的一种技术总称,比如我们通常见到的超声波、射线、渗透、涡流、磁粉等都属于是无损检测技术的范畴之内,它还包含着一些新的方法,比如超声相控阵、激光、红外、微波等无损检测方法,这些新的技术也受到了大家的广泛关注,它包括的很多原理以及技术特点在很多的领域得到了推广。 Non-destructive testing is a general term for several commonly used technologies. For example, ultrasonic, radiation, permeation, eddy current and magnetic powder are all commonly found in the field of non-destructive testing. We also include some new methods, such as Ultrasonic phased array, laser, infrared, microwave and other non-destructive testing methods, these new technologies have also been widely concerned about it, including many of the principles and technical features have been promoted in many areas.
