Understanding Magnetic Flux Leakage Signals From Gouges
2010 8th International Pipeline Conference, Volume 1, 2010The Magnetic Flux Leakage (MFL) technique is sensitive both to pipe wall geometry and pipe wall strain, therefore MFL inspection tools have the potential to locate and characterize mechanical damage in pipelines. The present work is the first stage of a study focused on developing an understanding of how MFL signals arise from pipeline gouges. A defect

Magnetic Flux Leakage Testing for Steel Plate Using Pot-Shaped Excitation Structure
IEEE transactions on magnetics, 2022U-shaped excitation structures are widely used to magnetize steel plates in magnetic flux leakage (MFL) testing. However, the edge effect leads to the difficulty of further increasing the magnetization near the defect as well as the leakage magnetic ...

Magnetic Flux Leakage for Bridge Inspection
Nondestructive Testing Methods for Civil Infrastructure, 1995For many years the Federal Highway Administration, and before that the Bureau of Public Roads, had focused its nondestructive evaluation program on development of better tools to inspect components of steel bridges. In the early 70s the emphasis was changed and attention was given to the need for an inspection device that would detect and assess the ...

Magnetic property evaluation using leakage flux spectrogram
International Journal of Applied Electromagnetics and Mechanics, 2007The validity of a new eddy-current-based damage detection technique was investigated. The Multi-Frequency Excitation and Spectrogram method (MFES) using Hall element sensor array was employed. Hall sensors positioned between the excitation yoke legs picked up leakage flux density in proportion to the excitation frequency. This new sensor configuration

Modelling Magnetic Flux Leakage Signals From Dents
2008 7th International Pipeline Conference, Volume 2, 2008The Magnetic Flux Leakage (MFL) technique is sensitive both to pipe wall geometry and pipe wall strain, therefore MFL inspection tools have the potential to locate and characterize mechanical damage in pipelines. However, the combined influence of strain and geometry makes MFL signals from dents and gouges difficult to interpret for a number of reasons:

Invariance transformations for magnetic flux leakage signals
IEEE Transactions on Magnetics, 1996Magnetic flux leakage (MFL) methods are used extensively for inspecting ferromagnetic materials. The analysis of the MFL signal is however fraught with problems associated with the sensitivity of the signal to a number of factors such as the MFL sensor velocity and variations in the permeability of the test specimen.
