welding of cast iron constructions. SUBSTANCE: electrode includes nickel base rod with coating applied onto it and containing, mas.%: barium fluoride, 5-52; silica, 2-10; ferromanganese, 5-11; ferrotitanium, 2-6; ferrosilicium, 5-11; graphite, 5-15; marble, the balance. Electrode rod is made of material including, mas.%: manganese, 2.5-6; ferrum, not more 2; copper, not more 3; titanium, not more 0.8; modifying components, not more 0.5; aluminium, not more 1.6; nickel, the balance. Electrode provides high quality welded seam having no slugging zones, pores, cracking at welding butt and angular constructions of high-strength cast iron in different space positions. EFFECT: improved chemical content of electrode. |
