Electrode for producing crack-free and tough welded joints. Weld metal is extremely metallurgical purity having very low hydrogen content. The electrode has a stable and concentrated arc, thus being well-suited or positional welding. Welds are of X-ray quality. CTOD-tested for offshore application.<\/p>\n\n\n\n
