Abstract: A computer-implemented method for evaluating echo signals obtained from a phased array experiment on a billet is disclosed. The computer-implemented method may comprise collecting the echo signals from a pulser/receiver unit, correlating the echo signals with a position on a longitudinal axis and a circumferential angle of the billet, computing an amplitude for each of the echo signals, displaying the amplitudes as indications in a c-scan data plot at a computer display unit, and determining the signal-to-noise ratios of indications located in a region-of-interest box relative to noise in surrounding boxes in the c-scan data plot. The computer-implemented method may further comprise classifying each indication as rejectable, reportable, or insignificant based on its amplitude and signal-to-noise ratio. The computer-implemented method may find applications in quality control evaluations in the aircraft industry.

Abstract: An example component inspection method includes directing a wave from a curved array of transducer elements toward a component. The method forms the wave using focal law calculator software.

Abstract: A system is provided for inspecting a workpiece that includes a workpiece defect and a workpiece surface. The system includes a laser pointer connected to an ultrasonic inspection system. The ultrasonic inspection system includes an ultrasonic transducer that directs sound waves to the workpiece defect, where the sound waves contact the workpiece surface at a workpiece surface location. The laser pointer directs a laser beam against the workpiece surface to visually annunciate the workpiece surface location.

Abstract: A method includes the steps of producing a first digital x-ray image of a part utilizing a full energy spectrum, producing a second digital x-ray image of the part with a hardened beam correlating to a higher energy portion of the full energy spectrum, subtracting the second x-ray image from the first x-ray image, and using a remainder of the subtracting step to locate the matter.

Abstract: Systems and methods for determining the velocity of ultrasonic surface skimming longitudinal waves on various materials are described herein. In embodiments, a surface skimming longitudinal wave is generated at a first location on a material, at least a portion of that wave is detected at a second location on the material, the time-of-flight of that wave between the first and second locations is determined, and then the velocity of that wave is determined. One or more crystallographic orientations of the material may then be determined based upon that velocity.
