Suitable for welding of steel constructions, bridge, dam, thermal power plants, petrochemical industry, shipbuilding, high strength pipe-lines, pressure vessels, tanks, which are dynamically loaded and require high mechanical properties. The weld metal has a very low hydrogen content and is resistant to ageing. Produces tough and crack-free welded joints, also suit for welding steels having a carbon content of up to 0.6% and rail joints. Good operating characteristic, also in root pass and positional welding. Very good gap bridging properties. Welds are of X-ray quality
