Transformation of the rotating eddy current testing signal at the desired eddy current orientation
NDT & E International, 2022 Abstract The results of rotating eddy current testing can be regarded as the results superposed by uniform eddy current testing in orthogonal directions. However, in the case of directional nondestructive testing problems, such as weld detection, only the results from the induced current that is perpendicular to the crack have the greatest ...
