Abstract
In order to extend the service life of commissioned NPP reactors, more stringent requirements are made of welded joints of equipment from 10GN2MFA steel, in particular, as regards limitation of impurities in weld metal. Evaluation of wire of Sv-10GN1MA type produced by ESAB was made to determine its suitability for manufacture of above-mentioned equipment. Comprehensive evaluation of deposited metal chemical composition, weld metal mechanical properties after respective heat treatment, radiographic testing of joints, determination of critical brittleness temperature allowed recommending the wire for application in nuclear engineering. 4 Tables.
