Nondestructive hydrogen content assessment of coated linepipe steel weldments via low frequency impedance measurements has been realized both in the laboratory and the field. A fundamental analysis of the plausibility of localized hydrogen-induced lattice strain detection in linepipe steel through low frequency impedance measurements is presented. Theoretical explanations of low frequency impedance measurements include free electron theory, quantum mechanics, and RKKY theory.
