Magnetic Flux Leakage Course of Inner Defects and Its Detectable Depth [PDF]
Chinese Journal of Mechanical Engineering, 2021 Abstract As a promising non-destructive testing (NDT) method, magnetic flux leakage (MFL) testing has been widely used for steel structure inspection. However, MFL testing still faces a great challenge to detect inner defects. Existing MFL course researches mainly focus on surface-breaking defects while that of inner defects is ...
