Abstract
The influence of thermal cycles of welding on the change of structure and mechanical properties of HAZ metal of welded joints of steel S390 (S355 J2) was studied. The range of admissible rates of cooling of HAZ metal in the temperature range of 600-500 °C was established, and welding consumables were selected ensuring welded joint properties on the level of requirements to the base metal, as well as their resistance to cold cracking.
