Eddy current technology has long been used in nondestructive testing (NDT) for wind turbine tower welds, drivetrains and a wide range of spot inspections in O&M programs. It’s a fast, accurate, chemical-free method for detecting surface and sub-surface indications that are too small to see with the naked eye, including cracks, pits, corrosion and damage due to impact or fatigue.

Eddy current testing has the added benefit of producing an electronic inspection record for advanced analysis and repor
