This paper studies the effect of combined welding of thick-wall gas and oil chemical equipment consisting of welding the weld root by automatic submerged-arc welding and electrosag welding (ESW) with the control of thermal cycles (CWC) of the main joint, on the corrosion resistance of welded joints in low-alloy normalized 16GMYuCh steel 50 mm thick. The chemical composition of the steel, % 0.16 C; 1.05 Mn; 0.25 Si; 0.42 Mo; 0.14 Ni; 0.1 Cu; 0.11 Cr; 0.049 Al; 0.032 S; 0.019 P. The authors determined the effect of cooling rate in the temperature range of diffusion transformation of austenite on the corrosion resistance of the weld zone. Attention was then given to the corrosion resistance of the welded joints produced by conventional ESW welding and ESW with CWC. The investigations show that the corrosion resistance of the parent metal is lower than that of the welded joints.
