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 …

Non-destructive eddy current testing (ECT) is widely used to examine structural defects in
ferromagnetic pipe in the oil and gas industry. Implementation of giant magnetoresistance …

High-speed inspection of inner diameter (ID) and outer diameter (OD) surface defects on
thick-wall steel pipes is an important aspect to advance the pipeline inline inspection (ILI) in …

Pulsed eddy current (PEC) responses would intersect at a point for a nonferrous plate when
only liftoff distance is varied. In this paper, the behaviors of liftoff point of intersection (LOI) …

A ferromagnetic material thickness quantification method based on the decay rate of the
Pulsed Eddy Current sensor detector coil voltage is proposed. An expression for the decay …

Based on time-domain analytical expression to pulsed eddy current field of a ferromagnetic
pipe, a least squares inverse problem, between the calculated and measured values of …

We developed a pitch-catch system based on electromagnetic acoustic transducers
(EMATs) for pipe inspection, which moves inside the pipe in the axial direction. The first …

The detection of surface and backside defects in steel plates is essential for safety
maintenance. Current ac magnetic flux leakage (ACMFL) testing systems generally operate …

Eddy current testing is widely used for nondestructive evaluation of metallic structures in
characterizing numerous types of defects occurring in various locations. It offers remarkable …

In the field of pulsed eddy current (PEC) testing, the lift-off effect can mix up the signal
