This paper proposes an injurious or noninjurious defect identification method from magnetic
flux leakage (MFL) images based on convolutional neural network. Different from previous …

Signals collected from the magnetic scans of metal-loss defects have distinct patterns.
Experienced pipeline engineers are able to recognize those patterns in magnetic flux …

Magnetic flux leakage testing (MFL) is the most widely used nondestructive testing
technology in the safety inspection of oil and gas pipelines. The analysis of MFL test data is …

Magnetic flux leakage (MFL) testing is widely used to detect and estimate defect in
ferromagnetic materials. The lift-off of sensors caused the weakening of the detected signal …

We have developed a simple sensor for imaging internal defects in materials using a
magnetically polarizable nanoemulsion. The gradient in the magnetic flux lines around the …
