Eddy Current Inspection

Eddy Current inspection uses the alternating magnetic field being induced into an electrically conducting material to generate a secondary alternating magnetic field. This secondary field in turn generates its own alternating currents (eddy currents). The method measures the activities of those opposed fields and currents and displays results of any changes encountered. Beside the conductivity mentioned, a number of properties influence the outcome of the inspections conducted. The method is suitable for inspection of surface and slightly sub-surface conditions, but the success of the method is relative to the parameters being applied. Well trained personnel, possible equipment and tooling, as well as the process control equipment being successfully applied guarantee the outcome of the techniques applied.

Correct parameters for a particular technique are essential, nevertheless interpretation of signal presentations may remain hard to do, based on the actual condition inspected for. With our expertise, we assure the optimum inspection environment for the inspector, and an increased sensitivity for the technique, or general repeatability and reliabilty conditions of the method.

Line Services can assist in determining and establishing the parameters referred to, and introduce and/or optimize the eddy current inspection method to meet your requirements.
