A

According to a survey conducted by the National Aeronautics and Space Administration, many non-destructive testing methods are considered to be divided into six categories and about 70 kinds. However, the following are common in practical applications:

Conventional non-destructive testing methods are:

－ Ultrasonic Testing（ UT）；

－Magnetic particle Testing（MT）；

－Penetrant Testing ( PT）；

－Eddy current Testing（ET）；

Unconventional non-destructive testing techniques are:

Acoustic Emission(AE)；

－Leak Testing（UT）；

－Optical Holography；

－Infrared Thermography；

－Microwave Testing
