Summary

Nondestructive Testing (NDT) methods may be classified under the physical principles that form the basis for each method. NDT methods may be classified under the physical principles that form the basis for each method. NDT methods are Penetrant testing (PT); Magnetic particle testing (MT); Eddy current testing (ET); Radiographic testing (RT); Ultrasonic testing ( UT ); and Acoustic emission testing (AE); Visual testing (VT); and Thermal infrared testing (TIR). Different types of waves or modes are used in ultrasonic testing. Particle motion in shear waves is perpendicular to the direction of the beam propagation. In most cases, shear waves are propagated at an angle to test object surface. However, when necessary, S-waves can be generated perpendicular to a test object surface, using a special transducer and couplant. There are two types of S-waves: vertically polarized shear waves (SVs) and horizontally polarized shear waves (SHs).
