Abstract
An automatic ultrasonic inspection system for automatically testing billets by the pulse reflection type of inspection and further utilizing an ultrasonic transducer for thru-transmission of energy for automatic distance-amplitude correction and including indexing means having an angular scan encoder and an axial scan encoder such that reflections obtained indicative of defects are accurately correlated with their three dimensional positions in the billets. A defect gate receives the reflections through the billet and if a defect meets a preset criteria such defect information is displayed and passed to a computer wherein the position of the defect is stored. The computer can provide various outputs such as alphanumeric-graphic display or printed outputs.
