Inspecting Power Network Analysis on Eddy Current Test of SMAW Joints

Eddy Current Test (ECT) is proven to be the most reliable non-destructive assessment for electrically conductive materials. This works based on emerging when an alternating current induced into The ECT system consists of three elements, i.e. injection, pick-up, and target. then treated as altered wireless power network between aforementioned elements. use (A/C) in this provides a wide variety spectra various analysis techniques. paper introduces novel technique subsurface crack SMAW welded joint stainless steel 316 L by applying response system. done constructing mathematical models frequency domain each component achieve gain model was constructed either defectless defected speciments, both result compared investigate extract information about crack. experiment also performed confirm simulation from modeling. succeeded differentiate size certain working frequencies.
