This paper describes the proposal of a benchmark activity. The objective of the proposed eddy current benchmark problem is to evaluate accuracy of various numerical or semianalytical methods in predicting an eddy current probe multi-frequency response. The probe has a complicated structure and it consists of a cylindrical ferrite core with five symmetrically placed columns. The probe was used to test plates made from nickel-base superalloy INCONEL 600. In the plate a set of defects were introduced. An AC currents consist of 15 harmonic components are applied to the excitation coils. In all cases the specimens were examined by placing the probe on the reverse side of the flaws. The acquired data will be send by email to all participants of the benchmark's activity.

In this paper a multi-sensor data fusion approach for eddy current measurements is presented. The fusion process based on Bayes decision theory and other classical fusion methods such as weighted averaging is carried out on raw signals and on signals processed by an artificial neural network. Multi-sensor data fusion algorithm enables to indicate potential cracks more precisely and with a higher probability of detection then it can be done using a single sensor. This will lead to better and more comprehensive evaluation of the tested objects.
