The effects of remanent magnetization on magnetic flux leakage signals
NDT & E International, 1997 The Magnetic Flux Leakage (MFL)Technique is the most commonly used technique to inspect large diameter transmission pipelines [1–5]. A typical MFL inspection system uses permanent magnets to apply an axially oriented magnetic field to the ferromagnetic pipe material.

An Opening Profile Recognition Method for Magnetic Flux Leakage Signals of Defect [PDF]
IEEE Transactions on Instrumentation and Measurement, 2019 The defect opening profile recognition is of great concern in the magnetic flux leakage (MFL) measurement technique. The detected spatial MFL signal has three components: horizontal, vertical, and normal components. Horizontal and normal component signals are commonly used to estimate the defect profile, while the vertical component has always been ...

Reduction of the Velocity Impact on the Magnetic Flux Leakage Signal [PDF]
Journal of Nondestructive Evaluation, 2019 The velocity effect on the magnetic flux leakage (MFL) signal was investigated in this paper. Experiments were performed for velocity of the MFL tool within the range of 0–2 m/s. The velocity was not constant during each measurement to imitate real operational conditions of the MFL tool. Two components of the leakage were measured, i.e.
