Welded joints of parts made of austenitic steel 12Kh18N10T and the precision alloy 29NK in which defects in the form of cracks arise are studied. It is established that the welds appears to be inhomogeneous in terms of chemical composition and grain size. It is shown that different factors that determine the magnitude of the stresses and deformations in welded joints influence the formation of cracks.

The study was carried out in the topic “Structure” as well as with the partial financial support of Grant 12-03-0050-a from the Russian Foundation for Basic Research and Project 12-U-2-1022 of the Presidium of the Ural Division of the Russian Academy of Sciences.
