The quantitative evaluation of defects is extremely important, as it can avoid harm caused by underevaluation or losses overestimation, especially for internal defects. magnetic permeability perturbation testing (MPPT) method performs well thick-walled steel pipes, but the burial depth defect difficult to access directly from a single time-domain signal, which not conducive In this paper, phenomenon layering magnetization that occurs in ferromagnetic materials under an unsaturated magnetizing field described. Different depths are achieved applying step magnetization. relationship curves between characteristic currents and established finite element simulations. spatial properties each be detected different layering. upper back boundaries then localized double-sided scan finally arrive at size defect. Defects with 2 mm evaluated experimentally. maximum relative error 5%.

The single nondestructive testing (NDT) techniques face the problem of low resolution when simultaneously detecting different types and locations defects. Composite inspection methods, which combine NDT techniques, have been widely studied due to their high defect detection accuracy. However, most existing composite methods require complex sensor systems or rely on signal-processing algorithms. Therefore, this article proposes a novel hybrid based electromagnetic acoustic transducer (EMAT) magnetic flux leakage (MFL) mechanism, allows accurately detect defects in ferromagnetic materials. This employs straightforward EMAT-MFL configuration, only requires permanent magnet generate requisite field for EMAT MFL components. In addition, it adopts unique orthogonal butterfly coil design cracks. obtained results show significant frequency difference between signals, demonstrates independence lack interference. eliminates potential issue signal aliasing decoupling. can fully use advantages technologies cracks top bottom surfaces Furthermore, wall thinning be detected with maximum error 4.48%. feasible approach miniaturizing sensors increasing performance.
