The presented application of the CS-pulsed eddy current technique on multi-layered rivet-joint aluminium specimen from the aircraft industry demonstrates function and possibilities of these technique with very promising results. Compared with continuous waves, pulses allow a higher current excitation, which lead to a higher signal to noise ratio in the receiving signal and consequently increases the sensitivity. The CS-technique supports a suppression of interference effects, of the sensor instead of a excitation. Beside a conventional eddy-current sensor, which is commonly used in aircraft industry for this task, a new rotating field sensor was introduced. This new sensor, which posses a sensibility independent from the orientation of the sensor to the defect orientation, proofed the ability of indicating the orientation of cracks. The results of this investigation show, that the CS-eddy current technique especially in combination with the rotating field sensor is a good approach to tackle the problem of bending crack detection in multi-layered aluminium structures.
