Summary

The ultrasonic inspection of a test object with a thick wall can be treated as an inspection of a semi-infinite medium. When the test object is a round cylinder with a relatively small diameter and the wavelength is greater than the diameter of the rod, cylindrical rod waves will be created with bar wave velocity, which is dispersive. This chapter discusses symmetric and asymmetric cylindrical rod-guided waves. To make the stud inspection as sensitive as possible, a probe with two transducers should be used: the beam from the first transducer will cover the upper zone of the stud L1 , and the second transducer beam will provide coverage of the lower threaded zone L2 . If the stud has a center-drilled bore, it is better to use conventional straight or angle beam techniques, applying the probe from the bore side.
