Probes,exotic configurations are included. Practically speaking, probes are often composed of more than one coil either for differential operation that is particularly effective in defect detection or so that each coil may be individually optimized for its role as drive or pick up coil. Some probes are ofCondescending 发表于 2025-3-28 19:05:09
Flaw Models,he purpose of showing how the various characteristics of a defect (its size, shape, location, and filler material, etc.) influence the observed change in impedance of the eddy- current coil. Two regimes are considered: the “small flaw” regime, when the flaw is significantly smaller than the electrom预测 发表于 2025-3-28 22:59:22

Chemische Technologie der Lösungsmittel the skin effect for EC NDE are discussed, utilizing the example of an air-cored eddy-current coil adjacent to an unflawed metal test-piece. For completeness, the electric displacement and polarization fields are also defined.CHAFE 发表于 2025-3-29 11:49:10
Säuren — Basen — Neutralisation — Hydrolyse with or without a ferrite core, and frequency of excitation current—are discussed. Test-piece factors—conductivity, permeability, shape, and position relative to the coil—are also discussed. Sources of uncertainty in inspections due to, for example, unknown variations in the coil windings or accide
