...Abstract Several offshore pipelines in Pre-salt fields, Brazil, are made of Super Duplex stainless steel. When welded, in general, these materials present a decrease in its corrosion resistance. Welding procedures, materials properties, surface conditions and post-weld treatment have influence...

... scenario. Welding processes are often used in applications involving this steel. However, in general, welding imposes a reduction in the corrosion resistance of stainless steels. Welding procedures, materials properties, surface conditions and post-weld treatment have influence on the resistance to local...
