Transient Eddy Current Analysis of Pulsed Eddy Current Testing by Finite Element Method

IEEE Transactions on Magnetics, 2004
Transient eddy current analysis of pulsed eddy current testing was performed by time-stepping method and Fourier transform method. The characteristics of two methods were evaluated by using a simple model. The accuracy was examined by the comparison of calculated and measured data.

Pulsed eddy current testing with variable duty cycle on rivet joints

NDT & E International, 2009
In pulsed eddy current testing, repetitive excitation signals with different duty cycles have different spectral representations. This work studies the influence of duty cycle on the ability to detect holes and EDM notches beneath rivet heads in subsurface layers of stratified samples. Feature patterns for the integrity of rivet joints are proposed and

Pulsed Eddy-Current Nondestructive Testing of Ferromagnetic Tubes

IEEE Transactions on Instrumentation and Measurement, 2004
In sinusoidal eddy current nondestructive testing (NDT) of thick ferromagnetic tubes, wall thickness is measured with the coils displaced for 2-3 tube diameters (remote field eddy current technique). The tube inner diameter is measured at higher frequency with another pair of coils displaced for around 1 tube diameter (electrical caliper).

Pulse Eddy Current Testing Thin Metal Thickness

2018 5th International Conference on Information Science and Control Engineering (ICISCE), 2018
The pulsed eddy current testing is commonly method that used for the detection of metal thickness. This paper takes the thin aluminum plate as the research object, uses Ansoft finite element simulation software, and uses the square wave pulse to stimulate the aluminum plate with different thickness to carry on the examination. It is found that the time-

Pulsed eddy current testing for gap measurement of metal casing

Measurement Science and Technology, 2022
Abstract A pulsed eddy current testing (PECT) method is proposed to measure the gap of non-ferromagnetic metal casing. Firstly, the detection sensitivity to the casing gap of the voltage signal induced respectively by time-harmonic excitation current and by pulsed excitation current are calculated theoretically and compared.
