Eddy Current Array (ECA)

Eddy Current Array (ECA) is an advanced form of conventional eddy current testing that uses multiple coils arranged in a specific pattern to simultaneously inspect a wide area of conductive materials. This technique offers faster scanning, improved defect characterization, and enhanced coverage compared to single-coil systems. ECA is particularly effective for detecting surface and near-surface cracks, corrosion, and other discontinuities in materials like aluminum or stainless steel, and is widely used in aerospace, power generation, and petrochemical industries.
