Eddy-Current NDT Near Steel Fasteners

Does anybody have experience and/or references on eddy-current measurements using DC magnetic field to saturate the magnetization of steel? Does anybody have experience and/or references on eddy-current measurements in proximity of steel fasteners? The only references I can find are work by Shepard, et al, at Northrup in USA.

Hocking NDT have experience of EC on fasteners. Using originally low frequency ring (donut) probes and latterly with our FastScan probe (a multi element dual frequency unit). We have detected 1 mm cracks in the second layer beneath a 2.5mm skin).

Visit our web site and download our probe catalogue.
