Abstract
A multizone ultrasonic inspection apparatus and method of employing the apparatus for inspecting titanium billets is provided, in which a plurality of ultrasonic transducers having focal zones of increasing depth are positioned to examine a cylindrical billet of titanium through the thickness of the billet. The focal zones partially overlap the adjacent focal zones, thus assuring complete examination through the thickness of the entire billet. The reflected signals from the transducer receivers are processed into digital form in order to be used in generating an image of the billet undergoing inspection, and to be used in storing the image data in, for example, a hard disk or an optical disk.
