A method of identifying a bond boundary between a sound bond and weak bond in a multilayer article may include determining a plurality of positions on a surface of the article; for each position of the plurality of positions, obtaining a full-wave, time domain waveform of ultrasonic waves reflected from the article; and, for each pair of adjacent positions among the plurality of positions, determining whether there is a bond boundary between a first position and a second position based on a comparison of a waveform characteristic of a first waveform generated at the first position and the waveform characteristic of a second waveform generated at the second position; and in response to a determination that there is a bond boundary between the first position and the second position, determining a boundary position based on the first position and the second position and memorializing the boundary position.
