Thermal Acoustic Imaging (TAI) methods and systems are provided for detecting defects in an object. The TAI system may include a plurality of acoustic wave transceivers (AWTs), which are positioned around the object at different locations, and a broadband frequency signal generator, which is coupled to each of the AWTs. The system may further include an acoustic processor configured to utilize the AWTs to gather acoustic data pertaining to the object, process the acoustic data to generate spectral response data, and then process the spectral response data to determine an optimized setup. The optimized setup may include optimized excitation frequencies and optimized inspection positions for positioning a plurality of infrared imaging devices at different locations around the object. A plurality of infrared imaging devices may then be selectively positioned with respect to the object at the optimized inspection positions and utilized to further inspect the object for defects.

Thermal acoustic imaging methods, systems, and apparatus for detecting defects in an object

A method for non-destructively evaluating a joined component includes inducing vibrations in the joined component within a range of frequencies, acquiring a resonance spectra from the joined component resulting from the induced vibrations, and analyzing the resonance spectra using Acoustic Sensor Testing (AST).

Methods for non-destructively evaluating a joined component

The disclosed embodiments generally relate to non-destructive evaluation methods. More particularly, the disclosed embodiments relate to ultrasonic non-destructive evaluation methods for the evaluation of friction welded bladed discs ('blisks'). In an embodiment, a method for non-destructive evaluation of a bladed disc structure includes identifying a region of interest on the bladed disc structure; positioning an ultrasonic transducer and receiver in the region of interest; scanning the region of interest using the ultrasonic transducer and receiver to produce a scan image; and comparing the scan image against a reference image to determine the presence of an anomaly in the region of interest.
