    METHODOLOGY FOR INSPECTION OF RIVETED SAMPLES BY THE ECA METHOD
    (Žilinská univerzita v Žiline, 2020) Janovec, Michal; Čerňan, Jozef
    The eddy current method is very often used technique of non-destructive testing and evaluation of materials. The method is very suitable for the detection of cracks that result from fatigue or cracking as a result of stress corrosion. Eddy current testing can be performed with minimal part preparation and a high degree of sensitivity. The eddy current method is used for the detection of surface and subsurface failures, corrosion in aircraft structures, holes for fixing various components and thread cracks. The paper describes the application of the eddy current method ECA in the inspection of riveted joints of the produced sample. The riveted sample is made of aluminum sheets and countersunk head rivets. Simulated damages are created around the rivet holes on the riveted specimen. Artificially formed notches simulate cracks around the rivet holes, and aluminum powder is used to simulate corrosion of aluminum sheets. These damages are then scanned with an Olympus OmniScan MX flaw defectoscop and the results of the measurements are evaluated in this article. SAB-067-005-032 and SBB-051-150-032 are used for non-destructive measurements.
