Abstract

Eddy current testing (ECT) with sensing coils placed orthogonally and connected in differential mode was applied to evaluate fatigue cracks in girth welds of clad pipelines. In the laboratory experiments, an automated inspection was performed with the goal to evaluate transducer’s detectability, and different scanning speed was tested to reproduce in service situation. Three samples of clad material with a 45° bevel weld were tested in a three-point bend fatigue machine, resulting in a fatigue crack located in the weld root of the clad sample. The results have confirmed that the introduced eddy current transducer is a potential solution for fatigue crack detection in clad circumferential weld root.
