FIELD: metallurgy. ^ SUBSTANCE: electrode can be used for welding with small 50°C temperature of tempering of martensite and bainitic class high-strength steel. To the bar of the electrode made of wire of sort "-033" or "-073" it is coated covering, containing component in a following ratio, wt %: marble 37.0-52.0, fluorspar 18.0-26.0, high-silica sand 3.0-10.0, titanium dioxide 3.0-12.0, ferrosilicon 0.5-5.0, ferrotitanium 5.0-14.0, ferromanganese or metallic manganese 1.0-5.0, rare-earth metals oxides 0.1-1.0, metal oxides 0.2-3.0, aluminium powder 0,2-4,0, sodium liquid glass to the mass of dry charge 23.0-28.0. Ratio of oxides content of rare-earth metals to content of iron oxides must be not less than 0.5. ^ EFFECT: electrode allows high efficiency and welding-functional specifications. ^ 3 tbl |
