From the discovery of eddy current phenomenon in 1851 to the adaptation of eddy current technology for industrial inspection applications in 1933, eddy current testing (ECT) has become one of the pillars of nondestructive testing (NDT).
Over the years, ECT has advanced and is recognized as being fast, simple, and accurate. The technology is now widely used in the aerospace, automotive, petrochemical, and power generation industries for the detection of surface or near-surface defects in conductive materials.
The demand for ECT has pushed the industry to create a better solution that saves time and resources and can substitute other methods of inspection. That solution is eddy current array (ECA).
ECA is a nondestructive testing technology that provides the ability to electronically drive multiple eddy current coils in a probe assembly. Each coil in the probe produces a signal relative to the phase and amplitude of the structure below it. This data is represented graphically as a C-scan image. Most conventional eddy current flaw detection techniques can be reproduced using ECA inspection, providing advantages such as improved inspection capabilities and significant time savings.
