This technique can detect surface and near surface irregularities in ferrous and non ferrous materials by inducing an eddy current field in the part under test.
This is a highly portable technique. The equipment is light, there is no need to remove any surface paint and it is ideal for on site applications, the inspection of aerospace parts and structures, including wheels and brake assemblies.
Specialised techniques are available for the on site inspection of tube bundles, typically in heat exchangers and air conditioning units.
