The possibility for improvement of welded joint properties by feeding cold wire into the weld pool to increase its cooling rate was considered. The technique of the process was investigated in the case of two-wire submerged-arc welding of low-alloyed 10G2FB steel at application of cold wire. Impact toughness of the metal of the weld and HAZ was determined on IX type specimens with a sharp notch to GOST 6996, depending on welding process parameters, and welded joint structures were studied.
Keywords: low-alloyed steel, thermal cycle, impact toughness, cold wire, submerged-arc welding
