This article presents two NDT methods: magnetic analysis of material state based on parameters of the structure-sensitive magnetic hysteresis loop (MHL) (coercive force, remanence, etc.) measured by an attachable magnetic transducer, and the stress-sensitive eddy current (EC) method based on changes in magnetic anisotropy of ferromagnetic steel under residual and operational stresses. Recent studies focus on NDT parameters sensitive to hydrogen concentration, with coercive force and residual induction being most responsive. The developed magnetic NDT method using an attachable transducer is relevant for the global energy industry. EC methods with magnetic anisotropy probes and alternating electromagnetic fields enable non-contact determination of mechanical stresses in surface layers of ferromagnetic steel components. Two applications of the magnetic anisotropy method are considered: determination of operational stress distribution in ferromagnetic steel pipelines and assessment of the balance between side walls during bridge framework launching to the abutments. Both applications were implemented using the developed stress analyzer with a surface EC probe. © 2026 The Authors. Copy from the contract: Published by ELSEVIER B.V.
