Eddy current testing (ECT) is one of the non‐destructive evaluation techniques widely used,
especially in oil and gas industries. It characterized noisy data to the less‐than‐perfect …

Lift-off variation causes errors in eddy current measurement of nonmagnetic plates as well
as magnetic plates. For nonmagnetic plates, previous work has been carried out to address …

Aluminum and its alloys have been widely used in aerospace and other industrial fields.
Aluminum and its alloy structures are prone to surface and subsurface cracks when they are …

Magnetic field imaging (MFI) is widely used in electromagnetic nondestructive evaluation
(ENDE). This paper presents a high-density, large-scale tunneling magnetoresistance …

Fast reconstruction of three-dimensional (3-D) defect profile from three-axis magnetic flux
leakage (MFL) signals is important to the pipeline inline inspection (ILI) in the oil and gas …

The development of eddy current nondestructive techniques and instruments is moving
toward new challenges in detecting buried and smaller defects and minimizing the …

This contribution focuses on the nondestructive evaluation of the thickness of metallic plates,
by means of eddy-current testing. Specifically, we present a method for reducing/optimizing …

Magnetic flux leakage (MFL) inspection in nondestructive testing (NDT) has been widely
used in damaged pipeline defect inversion. The changeable environment and the …

Non-destructive evaluation of materials and structures is still a key issue in some industrial
scenarios as the production process and the quality inspection. In the case of metallic …

In this paper, we present a fast method for classification of defects detected by eddy current
testing (ECT). This is done by using defects derived by lab experiments. For any defect, the …
