METHOD OF WELDING FERRITIC STAINLESS STEEL TO CARBON STEEL USING A FILLER MATERIAL MADE OF DUPLEX STAINLESS STELL; CORRESPONDING WELDED ARTICLE

摘要

A method of welding a ferritic stainless steel part to a carbon steel part is described. The method comprises arc welding (e.g. GTAW welding) the ferritic stainless steel part to the carbon steel part using a duplex stainless steel filler metal. Welded article made in this way is useful for industrial electrolyzers and particularly for corrosion resistant cathode and carrier plate assemblies in a sodium chlorate electrolyzer.
