Сварочно-технологические характеристики и механические свойства металла шва сварных соединений, выполненных проволоками ХОРДА 307 Ті и Св-08Х20Н9Г7Т

Abstract

A comparative evaluation of welding and technological properties, resistance to the formation of hot and cold cracks, using wires Sv-08X20N9G7T and HORD 307 TI. It is shown that the new welding wire of the domestic production of the brand HORDA 307 Ті is not inferior to the serial wire of the brand Sv-08Х20Н9Г7Т for welding-technological properties, the stability of the welding process, the mechanical properties of weld metal, the resistance of welded joints to the formation of cold and hot cracks, which gives grounds for recommending Its application to the welding of LBT structures in series production.
