Hello Frankie,

A description of ultrasonic testing of aircraft skin to core disbonds is contained under the literature section of Metals Testing Company's website www.mtc62.com

A description of eddy current testing of aircraft hidden corrosion is contained under the literature section of AMDATA NDE Technology's website www.amdatande.com

Both companies are exhibitors at NDT.net

Best regards,
Randy Plis

Hi Frankie,

These subjects make up a significant portion of our business here at SAIC Ultra Image International. We are currently doing work for the USAF involving hidden corrosion in aging aircraft using ultrasonic and eddy current methods. We also have much experience inspecting for disbonds in composite wing structures using ultrasonics. Please contact me at 860-442-0100 for further information. You may also want to visit our web site at http://www.saic.com/products/inspection/

Regards,

Mike

The NDE group at QinetiQ (previously DERA) in Farnborough have many years of experience with both ultrasonic and eddy current techniques on this type of application. They have reported on an ultrasonic technique for confirming that panel thinning is due to hidden corrosion (Smith, RA, Bruce, DA, 1998, An ultrasonic spectroscopy method for measuring the roughness of hidden corrosion surfaces, Proceedings of NDT'98, The British Institute of NDT, pp.167-170, ISBN 0 903132 26 5).

These techniques are applicable to area coverage by using high frequency integrated arrays specially developed by Diagnostic Sonar (for online info see http://www.bindt.org/Mk1Site/NDT2002Abstr2.html#Bending for recent abstract or http://www.galaxyscientific.com/agingaircraft/pdfs/6c/6c3d.pdf for an earlier full paper). These arrays can be used with flaw detectors or conventional mapping systems or with Diagnostic Sonar's Flaw Inspecta system (see http://www.ndt.net/article/v05n07/dlines/dlines.htm).

Digital Radiography for Concrete Inspection

In the construction industry (buildings, bridges) there is a need for fast non- destructive means,
...
most commonly to locate targets (Pipes, Re-bars, Conduit, Fittings etc.) within concrete structures prior to drilling, cutting or coring. Measuring reinforcements is also performed for static calculations and to detect corrosion problems and damages. Cracks and voids can also be visualized. The examinations are not only restricted to concrete constructions; they can also be applied to reinforced masonry made of natural stones or bricks.
