An ultrasonic fixture assembly for holding multiple ultrasonic transducers includes a mounting support rod for attaching the fixture assembly to a manipulator of a ultrasonic inspection system. A plurality of transducer mounting blocks may be mounted to the support rod by an elongated mounting bar or a single transverse mounting block may be mounted to the support rod. Each of the transducer mounting blocks will have a channel formed therein for slidably receiving an ultrasonic transducer or if a single transverse mounting block is used a plurality of channels will be formed through the mounting block. A central channel or a central transducer mounting block is provided for receiving and retaining a longitudinal wave type ultrasonic transducer and other channels or transducer mounting blocks disposed on either side of the longitudinal transducer are formed to hold shearwave type transducers. The shear transducer mounting blocks are pivotably mounted to the elongated support rod to permit positioning the transducers to provide a predetermined angle of incidence of the ultrasonic signal. A mechanism is also provided to permit adjustment of the water path length between the transducer and the surface of the workpiece.
