Re: Research groups on Eddy Current Our research and development group at RTD Quality Services bv. (Netherlands) is continually improving on the pulsed eddy current technology, with further developments to our RTD-INCOTEST system (Insulated Component Test)and other eddy current technologies. Another group that has conducted testing is EPRI, with whom we have been in discussions to advance the pulsed eddy current technology. Please see our Netherlands Web Page at www.rtdquality.nl or our North American page link.

Re: Research groups on Eddy Current : You are right. It is too big. : Actually, I am very intereted in the problem with corrosion and cracks in large diameter (>1m) iron pipes. There are thick coating (1cm) on the surface. . : Thanks. . Sounds to me like you should use Alternating Current Field Measurement (ACFM). This will inspect through thick non conducting coatings and is used on pipework welds in the offshore industry. Let me know if you want more details Don
