A new Factory Lab project is unveiled on Youtube. Its aim: to evaluate the effectiveness of alternative technologies to penetrant testing and magnetic particle inspection for non-destructive testing of parts.
What are the alternatives to penetrant testing and magnetic particle inspection for non-destructive testing of parts? This is the question posed by Safran Helicopter Engines, Bureau Veritas and Naval Group to CEA List and Cetim as part of the Factory Lab Alter project, which is explained in detail in a video posted on Youtube.
In this exploration of tomorrow's NDT, which will replace solutions that are effective but incompatible with in-line inspection and less and less compatible with respect for the environment, CEA List and Cetim have each explored a different avenue: multi-element eddy currents for the former, and infrared induction thermography for the latter, for the inspection of turbine blades supplied by the world's leading helicopter turbine manufacturer.
The result of this in-depth study: for Bureau Veritas and Safran Helicopter Engines, the advantage goes to infrared induction thermography. Furthermore, " This project has opened up the possibility of working on digital, non-contact and automatable methods that can be integrated in-line. This will reduce the logistical cycles involved in transferring parts to the penetrant testing line. "says Thomas Groursolle, R&T, DI Process Engineer at the helicopter engine manufacturer. However, the eddy current method has also proved attractive to Naval Group, thanks to its portability.
