Heavy coated basic type electrode for welding fine grained structural steels and especially cryogenic steels, subjected to low service temperatures up to -60°C. Electrode produces tough and crack-free welded joints. Weld deposit is of extremely high metallurgical purity and very low hydrogen content. Owing to high crack resistance under difficult conditions such as dynamic loads, impact, vibration and low service temperatures, it is suitable for use in welding of storage tanks and piping. Suitable for use in root passes and joints in pipes and equipments of cold storage rooms with service temperatures down to -60°C. Electrode features a stable and concentrated arc. Especially 2,50 mm and 3,25 mm diameters are well-suited for positional welding. Welds are X-ray quality.
