Pulsed Eddy-Sonic Test Method Shurtronic Harmonic Bond Tester

3 Pulsed Eddy-Sonic Test Method (Shurtronic Harmonic Bond Tester) 

This method can detect both near-side and far-side unbonds in many types of honeycomb and laminar structures. It can also detect crushed core, fractured core, and excessive build-up in repaired structures. At least one of the surfaces must be electrically conductive to some extent.
