heal.abstract	Fast water cooling rates in duplex stainless steel (DSS) welds results in a decrease of the width of the ferritization zone to 500 μm compared to 600 μm in the case of air-cooling. Although the austenite volume fraction of the weld zone decreases in water-cooled welds, this fraction of 43% is high enough to provide sound corrosion and mechanical properties for the weld. The hardness of the welded area is affected by the cooling rate, as a direct consequence to the different structures of the welding zones. Water-cooling gives harder weld metal than air cooling, due to the higher volmue fraction of the harder ferrite. Fast water-cooling subsequent to welding decreases also the toughness of the weld.	en
