Heavy coated basic type electrode with high efficiency, which is for welding low alloy steels, fine grained structural steels and high strength pipes. Due to it's high crack resistance under difficult conditions such as dynamic loads and service temperatures between -60°C and 450°C, it is suitable for use in heavy steel structures, off-shore platform, heavy machinery, pressure vessels, tanks, boiler production, welding and repair jobs of pipes and in their root pass applications. Welds are of X-ray quality..
