Eddy Current Testing, an Emerging NDT Method for Ferritic Weld Inspection

摘要

This article discusses the emergence and acceptance of manual eddy current weld inspection as a high quality and cost saving NDT method for in-service inspections. In a recent American Welding Society journal article on NDT, eddy current testing was not mentioned as a basic weld inspection method (AWS, 1997). In fact, it has become common in the European sector, and American oil and gas companies are now beginning to use eddy current.
