Abstract:
1. A method for inspecting joined material interfaces comprising the steps of: transmitting a plurality of acoustic waveforms onto a joined material interface at an angle greater than 0° and less than 90° with respect to an orientation of said joined material interface; detecting a reflected waveform reflected from said joined material interface for each of said acoustic waveforms; dividing said acoustic waveforms into a plurality of time zones, each said time zone beginning at a time of detection of a corresponding said reflected waveform and ending after a predetermined amount of time; determining a waveform amplitude for each said acoustic waveform within each said time zone; comparing said waveform amplitude against a predetermined waveform amplitude, said predetermined waveform amplitude representing a calibration amplitude for an acceptable said joined material interface; and determining a quality of said joined material interface based upon said comparison of said waveform amplitude with said predetermined waveform amplitude.
