Webb10 sep. 2002 · Actual eddy-current testing times of 100 milliseconds are easily achieved. Handling and positioning of the component with respect to the probe can add up to a few seconds. This is consistent with most production line processes. The material-handling system must be configured to handle rejected parts. Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials. Visa mer Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering … Visa mer The two major applications of eddy current testing are surface inspection and tubing inspections. Surface inspection is used extensively in … Visa mer • Eddy current • Nondestructive testing • Alternating current field measurement • Cover Meter Visa mer In its most basic form — the single-element ECT probe — a coil of conductive wire is excited with an alternating electrical current.
