Benefits. Mobile. Portable. 2021-02-26 2021-03-25 In seismology, S waves, secondary waves, or shear waves (sometimes called elastic S waves) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.. S waves are transverse waves, meaning that the oscillations of an S wave's particles are perpendicular to the direction of wave propagation Shear wave testing, also known as angle beam inspection, is an ultrasonic testing technique used primarily for weld inspections. A probe consisting of an ultrasonic transducer coupled with a plastic or epoxy wedge introduces an ultrasonic beam at an angle into a test area.

This surface following wave is sometime referred to as a creep wave and it is not very useful in NDT because it dampens out very rapidly. Beyond the first critical angle, only the shear wave propagates into the material. For this reason, most angle beam transducers use a shear wave so that the signal is not complicated by having two waves present.
