A global centralized magnetic flux leakage small defect detection network

Engineering Research Express
Abstract To solve the problem that magnetic-flux-leakage (MFL) small defects are difficult to accurately detect by machine learning methods, a global centralized magnetic flux leakage small defect detection network (RCFPNet) is proposed. RCFPNet consists of simulation data enhancement, improved feature extraction (backbone), an improved ...

The research on defect recognition method for rail magnetic flux leakage detecting

Proceedings of 2012 International Conference on Measurement, Information and Control, 2012
In this paper, the ANSYS finite element software was used to establish a two-dimensional mathematical model of defect leakage field for the simulation of the cracks, cone-shaped, pits and other regular defects of rail with the FEM simulation method, through which axial and radial magnetic flux density distribution curves and other data of defect ...

A New Micro Magnetic Bridge Probe in Magnetic Flux Leakage for Detecting Micro-cracks

Journal of Nondestructive Evaluation, 2018
Magnetic flux leakage (MFL) testing has been widely used as an efficient non-destructive testing method to detect damage in ferromagnetic materials. It’s of great importance to improve the testing capability of MFL sensors. In this paper, a micro magnetic bridge method in MFL of high sensitivity is proposed to detect micro-cracks.

Magnetic Flux Leakage Detection of Corrosion Damage in Prestressed Concrete Poles

2015
Urban infrastructure includes large amounts of concrete poles which support power lines, communication cables, and street lighting. These poles are made of spun concrete with embedded pre-stressed reinforcement steel. The chemical environment at the ground-air interface, in combination with tensile prestressing and possibly low concrete cover, promotes

Importance of magnetic saturation effects in the detection of internal tube cracks by magnetic flux leakage

1992
A mathematical model is used to analyze the possibility of detection of cracks on the internal surface of steel tubes by the magnetic flux leakage technique. A linear model shows that the signal from an internal flaw is more than one order of magnitude weaker than that from a similar external defect.
