The paper presents the results of investigation of pore formation in the metal of welded joints in steam lines operating for a long time under creep conditions. Features of pore formation in the regions of welded joint HAZ were revealed that allows improvement of diagnostic assessment of their residual life. Critical threshold of welded joint damage is local density of micropores of 0.8 μm and larger size on the level of 1500-1800 pores per mm². 7 Ref., 7 Figures. [ABSTRACT FROM AUTHOR] |
