Eddy Current Testing (ECT) uses electromagnetic induction to detect flaws in conductive materials like cracks, corrosion via coil-generated eddy currents. Tove Leeds inspects heat exchanger tubes, aircraft, welds, tanks with surface probes, bobbin coils, arrays.

Multi-frequency optimizes detection: high for surface cracks, low for subsurface. Serves power (tubes), aerospace (fatigue), oil & gas (pipelines), automotive (alloys).

Advantages: sensitive, fast, through-coatings, no couplant. ASNT/ISO-trained techs calibrate standards, produce C-scan reports for maintenance, per ASNT SNT-TC-1A.
