The Alternating Current Reid Measurement (ACFM) crack detection and sizing technique has demonstrated its potential as a stress corrosion cracking (SCC) characterization tool in studies conducted at Memorial University of Newfoundland (MUN). It’s ability to detect and size cracks through non-conductive coating thicknesses of 5 mm or more can have a significant impact on the costs associated with the current SCC investigation practices of many gas and liquid fuel transmission companies.

This paper outlines work conducted at MUN in automating the detection of SCC within ACFM signals. The technique may be refined and incorporated into SCC characterization procedures.
