Pulsed Eddy Current Non-destructive Testing and Evaluation: A Review
Pulsed eddy current (PEC) non-destructive testing and evaluation (NDT&E) has been around for some time and it is still attracting extensive attention from researchers around the globe, which can be witnessed through the reports reviewed in this paper. Thanks to its richness of spectral components, various applications of this technique have been proposed and reported in the literature covering ...
متن کاملPulsed eddy current empirical modeling
The pulsed eddy current responses to varying material thickness and conductivity are modeled using an electrical circuit ideal transformer non-linear model. The Levenberg-Marquardt algorithm is used to curve fit the experimental signal to the model. The resulting synthetic signal is examined for its ability to preserve experimental signal features such as lift-off point of intersection (LOI), a...
متن کاملAutomated Pulsed Eddy Current Method for Detection and Classification of Hidden Corrosion
Corrosion has an important effect on the structural integrity of aging aircraft components, and an automatic and effective method of corrosion detection and classification can help to ensure the safe operation of a transportation system. Pulsed eddy current (PEC) has been shown to effectively characterize hidden corrosion in aircraft fuselage lap joints. However, two noise sources in the form o...
متن کاملA Steel Ball Surface Quality Inspection Method Based on a Circumferential Eddy Current Array Sensor
To efficiently inspect surface defects on steel ball bearings, a new method based on a circumferential eddy current array (CECA) sensor was proposed here. The best probe configuration, in terms of the coil quality factor (Q-factor), magnetic field intensity, and induced eddy current density on the surface of a sample steel ball, was determined using 3-, 4-, 5-, and 6-coil probes, for analysis a...
متن کاملWavelet based signal analysis of pulsed eddy current signals
This paper deals with response signals processing in eddy current non-destructive testing. Non-sinusoidal excitation is utilized to drive eddy currents in a conductive specimen. The response signals due to a notch with variable depth are calculated by numerical means. The signals are processed in order to evaluate the depth of the notch. Wavelet transformation is used for this purpose. Obtained...
