It is shown that under the influence of the thermal cycle of welding, the mechanical properties of the metal change, namely, with an increase in the cooling rate of the metal W6/5, an increase in strength characteristics, and a decrease in the parameters of plasticity, and impact strength are observed. Steel S460M, obtained by controlled rolling, can be used in the manufacture of welded steel structures do not require hot-working operations and stamping. It is allowed to heat no higher than AC1, to remove welding stresses. It is also possible to foresee cold stamping, given that the steel has high ductility. Steel S355J2, obtained by normalization, can be used in the manufacture of welded steel structures in which operations with a temperature of their conduction up to 950 С are foreseen.
