FIELD: automatic welding of low-alloy cold-resistant steels of high and very high strength by means of low-carbon and low- alloy wires in any branch of industry.
SUBSTANCE: ceramic flux includes next relation of ingredients, mass %: roasted magnesite, 26.4 - 30.0; synthetic corundum, 18.6 - 22; fluorspar, 20.0 - 20.5; sphene concentrate, 12.2 - 14.5; synthetic titanium dioxide 98%, 5.0 - 6.5; manganese metallic, 2.0 - 3.1; ferrotitanium, 0.25 - 0.5; ferrosilicon, 0.5 - 0.8; titanium magnetite, 0.5 - 0.63; ferroboron, 0.2 - 0.4; sodium-potassium silicate, 6.55 - 8.1. Such flux allows use small cost low carbon wires instead of high cost low alloy and alloy wires for welding important structures operating at negative temperatures (40)-(-60)°C.
EFFECT: enhanced manufacturing properties at welding butt joints with deep dressing of their edges.
