Basic electrode, core wire alloyed, for welding of ferritic-austenitic duplex materials. Besides the high tensile strength, the special advantage of the weld metal of this electrode is its very good toughness behavior down to –60 °C. Furthermore, the high crack resistance of the weld metal and the particularly good resistance to stress corrosion cracking and pitting behavior are significant features. The electrode provides user operating characteristics in all positions except vertical down with good slag removability and weld bead appearance. Additionally, the filler metals offer high safety against the formation of porosity.
