The problem of ensuring the reliability and strength of equipment and structures operating at low climatic temperatures is an urgent scientific and technical task today. Ensuring sufficient cold resistance and strength means preventing brittle fracture of structural elements at loads that are significantly lower than the calculated ones. One of these characteristics is impact strength. The paper presents the results of studies of the impact strength of a welded joint of steel 10ХСНД obtained by DC welding and pulsed arc welding.
