Abstract—The paper presents the results of a comprehensive study of structural and property changes in the most dangerous regions of the heat-affected zone of low-alloy cold-resistant steel with a guaranteed yield strength of 355–390 MPa before and after the post-welding tempering, including those caused by the combined impact of heating temperature under tempering and deformation, compared to base metal. The simulation was performed using a DIL 805 dilatometer and a Gleeble 3800 complex. The results of the investigation of the structure and properties of actual welded joints after welding with different rates of energy input (3.5 and 6 kJ/mm) are presented.
