Abstract:

The present invention is related generally to the field of non-destructive materials testing using ultrasonic devices, more particularly, ultrasonic devices in a phased array and includes a wedge for conducting pitch-catch ultrasonic phase array testing of materials wherein the wedge includes a liquid column and is manufactured with specific angles so as to control the angle at which the ultrasonic waves pass into the wedge and then are refracted when passing from the liquid in the liquid column into the material being analyzed, thus providing a wider range of analysis via sweeping the beams from the wedge than was possible with known wedges.
