PURPOSE: A nickel-substrate alloy is provided to obtain welds having excellent ductility, hardness, and corrosion resistance while being easily wire drawn and hot rolled for being used to weld a product formed by super duplex or super austenite stainless steel. CONSTITUTION: A welding electrode includes a wire or a strip formed by a nickel-substrate alloy. The welding electrode is composed of 20-24wt% of Cr, 8-12wt% of Mo, 0.1-5wt% of W, over 12wt% of Mo+W, under 5wt% of Fe, under 0.1wt% of Cu, under 0.1wt% of N, under 0.02wt% of C, under 0.1wt% of Si, under 0.4wt% of Mn, 0.03-0.4wt% of Al, 0.004-0.04wt% of Mg, under 0.02wt% of P, under 0.02wt% of S, and the remnant wt% of nickel and impurities generated by refining.
