Wire Rope Testing – An Introduction to Magnetic Flux Leakage Testing

Updated: Jul 31, 2020


Wire rope testing with magnetic flux leakage (MFL) is a well-developed non-destructive testing (NDT) technique for wire rope inspection. The measurement instrumentation is designed to detect local faults (LF) and loss of metallic area (LMA). Local faults are generally wire breaks while loss of metallic area is generally categorized as a gradual or extended loss in cross-sectional area due to corrosion, wear, or other wire rope deterioration mechanisms. This article introduces the reader to the MFL wire rope testing hardware and data.
