Suitable for welding steel constructions, bridges, dams, thermal power plants, petrochemical industry components, shipbuilding, high-strength pipelines, pressure vessels, and tanks that are dynamically loaded and require high mechanical properties. The weld metal has a very low hydrogen content and is resistant to aging. It produces tough and crack-free welded joints and is also suitable for welding steels with carbon content up to 0.6%, as well as for rail joining. Offers excellent operating characteristics, including in root passes and positional welding. Provides very good gap-bridging capability. Welds are of X-ray quality.
