Shearwave transducers are a single or dual element device mounted on an angled wedge, and are typically used to introduce a refracted shear wave into the test material and can be purchased in a variety of fixed angles.

Shearwave TransducersDue to differences in material velocities the angle of refraction that is marked on the transducer is only accurate for a particular material, which is usually steel. The angled sound path allows the sound beam to be reflected from the back wall to
improve detectability of flaws in and around welded areas. They can also be produced to generate surface waves for use in detecting defects on the surface of a component.

Shearwave TransducersNormal incidence shearwave transducers allow the user to introduce a sound wave into the test piece at an angle with minimal longitudinal wave refraction.

All elements are available in rectangular or round format and can be manufactured to suit the customer’s specification.
