Improvement of the Service Properties of the Weld Joint Metal for Transport Nuclear Power Units Manufactured of Heat-Resistant Steel Grades: Part III. A Study of the Influence of Alloying Elements on the Characteristics of the All-Weld Metal as Applied to the Fabrication of Low-Carbon Metal Deposits and Assembly Weld Joints in Icebreaker Nuclear Power Units

The influence of alloying elements, namely, silicon, manganese, nickel, and molybdenum, contained in the welding wire on the mechanical properties of the metal of automatic submerged-arc welding joints has been investigated. It has been established that the required strength and ductility values and the ductile-to-brittle transition temperature of the weld metal both in the as-welded state and upon high-temperature tempering are achieved by using welding wire with a silicon content of ~0.6% and a manganese content of ~1.5%.
