Abstract: Abstract of the Disclosure In a new method and apparatus for ultrasonic inspection of objects each inspection device of the apparatus is fed by gravity with a supply of a liquid coupling medium, from which the device produces a liquid stream that is directed at the object.          The device mounts  a focusing ultrasonic transducer that generates an ultrasonic beam in the liquid focused at a downstream point not less than about 5 cm from the oscillation generating surface.          The external envelope of the ultrasonic beam is contained wholly within the external envelope of the liquid stream with a separation between them at least until the object is impinged by the liquid stream.  The liquid feed is made as non-turbulent and entrained bubble-free as possible to avoid the generation of unwanted back-ground noise and spurious signals.  The increase in distance through which inspection can be effected simplifies the application of the method to testing pipe wall and lamina thickness and to the testing of bulky bodies such as aeroplane wings.  It also permits the application of the method and apparatus to the in situ testing of the wall thickness of well pipes.
