Translated from Metallurg, No. 9, pp. 71–76, September, 2014.
Lamellar tearing may develop in building metal structures using low-carbon steels in welded joints and assemblies. A reason for its occurrence is an inadequate level of ductility with respect to the degree of welded structure stress in the plate thickness direction. Using results of thick plate tests, we demonstrate the effect of harmful impurities and also strength level, structural inhomogeneity, and low-carbon steel slab thickness on the level of relative reduction of area in the thickness direction of plate produced in the NLMK DanSteel 4200 rolling mill.
