AbstractA phased array transducer design for billet inspection is presented. The transducer sweeps a uniform focus in both depth and angle to assure uniform coverage of the billet volume, particularly at the billet center, where coverage depends critically on transducer alignment. Design concepts are presented which enable the transducer to sweep a tight focus in both depth and angle using 63 discrete time delays. Design concepts and specifications are summarized, and experimental verification of design performance is presented. Data acquisition protocols are discussed enabling the phased array inspection to operate at production speeds.
