Abstract:
1. A method for non-destructively evaluating a joined component, comprising: providing the joined component that comprises either a dual-alloy component or a solid-state joined component; inducing vibrations in the joined component within a range of acoustic frequencies by placing a first transducer along a joint of the joined component, wherein inducing vibrations within a range of acoustic frequencies comprises inducing vibrations within a range of frequencies that is a subset of the range of frequencies from 20 Hz-20 kHz; acquiring waveforms or fast Fourier transforms (FFT) or both as a resonance spectra from the joined component resulting from the induced vibrations by placing a second transducer along the joint of the joined component; and analyzing the resonance spectra using process compensated resonant testing/acoustic sensor testing (AST).
