AB This essay synthetically presents a selection of technological properties of EN-GJS-500-7 Spheroidal cast iron castings and a selection of applications of spheroidal cast iron in the function of its chemical composition. The concept of the surface layer (SL) was defined, its classification and basic elements of its structure were provided. The essay presents the results of the Davidenkov's method research on internal stresses in the surface layer of the cast iron castings (in weld surfaced half products appropriated for preforms and glass moulds). The results of the research clearly show that the values of stresses occurring during weld surfacing depend on the thickness of the weld surfaced layer. Moreover, the research has determined an important influence of the thickness of this layer on the stresses in the base material (core).
