Surface Eddy Current Tubular Inspection

Eddy current array and conventional eddy current technology share the same basic principle. Alternating current injected into a coil creates a magnetic field When the coil is placed over a conductive part, opposed alternating currents (eddy currents, in red) are generated. Defects in the part disturb the path of the eddy currents (in yellow). This disturbance can be measured by the coil.

Advantages of ECT testing

Reduced need for complex robotics to move the probe; a simple manual scan is often enough Inspection of complex shapes using probes customized to the profile of the part being inspected.
