Eddy current thickness testing
WebTesting with magnetic thickness gages is sensitive to surface roughness, curvature, substrate thickness, and the make up of the metal alloy. ... Eddy current coating thickness gages (e.g. PosiTector 6000 N Series) look … WebEddy current testing is an effective non-destructive testing method to inspect a pipe from its inside [3]. Therefore, an ECT experiment was carried out on the F82H short pipe with flaws, and the flaw on the inner surface was detected [4]. However, the strong magnetic property of F82H hampers induced eddy currents from penetrating the pipe wall.
