AbstractThe electrophysical system of non-destructive testing is tested on the NPP operating process equipment. The welded joints of the process pipeline located in the turbine hall are selected as the object of control. The results of the study confirm that the base metal of the welded joints is in a plastically deformed state. A comparison of the results of testing welded joints by scanning contact potentiometry and magnetic anisotropy methods is presented.
Keywordsscanning contact potentiometry method, non-destructive testing of welded joints, magnetic anisotropy method.
