Development of a pulsed eddy current instrument and its application to detect deeply buried corrosion
<p>Eddy current techniques have historically been valuable to nondestructive evaluation and testing. They allow detection of cracks, corrosion, and other inhomogeneities in conducting materials. However, due to the fact that traditionally eddy currents only use one frequency to excite the coil, …

Inspection of Ferromagnetic Support Structures From Within Alloy 800 Steam Generator Tubes Using Pulsed Eddy Current
… rated for large radiation fields. Conventional eddy current testing (ECT) and ultrasonic testing are currently employed for inspecting SG tubes, with the former doing most inspections due to speed and reliability based on an understanding of how flaws affect coil impedance parameters when …

Eddy current detection of fatigue cracks in drill pipes
… with non-destructive testing (NOT). The eddy current method is an ideal NDT technique as it does not require contact with the test surface and is highly sensitive to fatigue cracks .. However, this method is generally only sensitive to surface and near surface defects. This proves to be a …
