Eddy current testing (ECT) is an electromagnetic testing technique used to inspect non-ferromagnetic materials, and eddy current array (ECA) is an advanced form of ECT that allows efficient scanning over larger areas. 

Eddy current array (ECA) technology has long been used for nondestructive testing in aerospace, power generation, oil and gas, and other industrial applications. It’s a fast, accurate, chemical-free method for detecting surface and sub-surface indications including cracks, pits, corrosion, and damage due to temperature or fatigue.

Conventional eddy current technology has been used for many years to inspect the surfaces and subsurfaces of various components across a wide range of industries.

Eddy current testing (ECT) is a nondestructive testing (NDT) technique used to detect surface and sub-surface defects using principles of electromagnetic induction.

The recent advent of more affordable industrial robots and controls has enabled the development of fully automated eddy current testing systems that improve flaw detection and reduce inspection costs.

The 454A’s primary advantage is its ability to be integrated into an automated system.

While advancements in automation and technology have enabled efficient acquisition of large volumes of nondestructive examination (NDE) data, the advancements in the analysis of collected data have been largely stagnant.
