The results of investigations of the properties of electrode compounds, coatings and electrodes of rutile-basic type were set forth and analyzed. These electrodes are designed for welding of high-strength Cr–Ni steels depending on composition of lithium-containing liquid glass. It is shown that application of Li–Na–K liquid glass for manufacture of such electrodes allows significantly improving their hygiene and sanitary properties due to reduction of specific emissions of hexavalent chromium high-toxic compounds. Simultaneously, application of Li–Na–K glass results in significant decrease of hygrosorption capacity of the coating, at that its strength and crack resistance in welding do not deteriorate, and ductility and impact toughness of weld metal is somewhat improved. The workability indices and welding-technological characteristics of compared electrodes are at the same level. The results of the investigations allowed upgrading coating composition and production technology of ANV-35 electrodes. 23 Ref., 9 Tables, 2 Figures.
Keywords: high-alloy Cr–Ni steels, arc welding, coated electrodes, binders, processing characteristics of electrode compounds, strength and hygroscopic properties of electrode coatings, welding-technological and hygienic properties of electrodes, composition and structure of deposited metal, mechanical properties of weld metal
