Niezgodności w złączach zgrzewanych metodą FSW i nieniszczące metody ich wykrywania

Języki publikacji

Abstrakty

The article presents the classification of imperfections present in joints welded using the FSW method. The division of imperfections is based on standards PN-EN ISO 25239:2013 and AWS D17.3. The article also provides a more extensive and precise division of welding imperfections characteristic of the FSW process along with reasons for their formation. The text also presents the requirements of the standards in relation to the boundary values of imperfections depending on imperfection types. Furthermore, the article demonstrates the advantages, disadvantages and application of given non-destructive tests with reference to the quality control of FSW joints.

Przedstawiono klasyfikację niezgodności, jakie występują w złączach zgrzewanych metodą FSW. Podział niezgodności został dokonany w oparciu o normy PN-EN ISO 25239:2013 i AWS D17.3. Podano również szerszy i bardziej precyzyjny podział niezgodności zgrzewalniczych charakterystycznych dla procesu FSW wraz z przyczynami ich powstawania. Przybliżono wymagania norm w zakresie granicznych wartości niezgodności w zależności od rodzaju niezgodności. Przedstawiono wady, zalety oraz zastosowanie danych metod badań nieniszczących w odniesieniu do kontroli jakości złączy FSW.
