Abstract
Pulsed eddy current (PEC) technique applied on inspecting metal surface cracks from theoretical and experimental aspects will be demonstrated in this work. In the previous work, we have showed that the PEC technique can be used to inspect surface cracks with depth 0.5 mm to 9 mm. The results showed that the relationship between PEC signals and crack depth is obvious. In this work, we further study this topic from both experimental and theoretical aspects. Experimental results including fatigue and nuts measurements are showed and compared. We also review related theories of time-domain PEC signals predication that based on transformation from frequency-domain theoretical calculations.
