A method and apparatus for ultrasonic inspection of one or more objects in an object holder. In a first embodiment of the method, the objects are immersed in a tank containing coupling fluid and a flow of fluid is generated in the tank beneath the object holder, thereby producing a suction pressure that tends to hold the objects in the holder. Each object is insonified with ultrasound from an ultrasonic transducer and the ultrasound reflected from or transmitted through the object is sensed. In a further embodiment, the object to be inspected is moved between the upper and lower chambers of a scanning station, over a surface in the lower chamber. A coupling fluid is supplied to the upper chamber so that coupling fluid flows through one or more holes in the bottom of the upper chamber and fills the space between the ultrasound emitting surface of the ultrasonic transducer and the object to be scanned, thereby providing coupling for the ultrasound and tending the hold the objects in the object holder.
