Angle Beam Transducers are used for testing of weld integrity. Angle beam transducers are single element transducers used with a wedge to introduce a refracted shear wave or longitudinal wave into a test piece. They are also used to generate surface waves for use in detecting defects on the surface of a component. Angle beam transducers allow inspections in areas of a part that cannot be accessed by the ultrasonic path of a normal incidence contact transducer. A common use for angle beam transducers is in weld inspection, where a weld crown blocks access to the weld zone of interest for a standard contact transducer and where typical flaw alignment produces stronger reflections from an angled beam. Angle beam transducers include mounted transparent angle blocks and are used for weld inspection & flaw detection.
