Description

The objective of the ongoing work reported here is to optimize pulsed eddy current instrumentation for the detection of small flaws, specifically 250 × 125 pm crack-like defects in low conductivity materials such as titanium 6-4. Our approach parallels that employed in the optimization of continuous wave eddy current systems1,2 in that we seek first to develop a mathematical model of a typical flaw detection system, and then use the model as a guide in the design of probe instrumentation and in the selection of signal processing methods to enhance flaw detectability.
