ABSTRACT:
The invention provides apparatus for ultrasonically testing the edges and/or the body of a metallic workpiece, utilizing water as a coupling medium between ultrasonic transducers and a metallic product moving relative to the testing apparatus along a predetermined pathway; which apparatus comprises guide means defining the pathway to be followed by the metal product, one or more reservoirs being the pathway each incorporating a top opening through which water can overflow to contact successive parts of the piece to be tested, located thereabove and a plurality of ultrasonic transducers located in one or more groups within the reservoir or reservoirs and directed towards the edge or body of the piece to be tested so that they may be static, adjustable transverse to the direction of movement of the product along the pathway, or reciprocate in a sinusoidal manner to traverse all or part of the pathway.
