<br/><br/> The superduplex stainless steels have an austeno- ferritic microstrcture which leads to better mechanical properties and corrosion resistance than austenitic stainless steels . In this research we focus on characterization and analysis of a multipass weld joint of UNS S32750 SDSS and UNS S31050 ASS similar and dissimilar weldments welded in conditions equal to industrial standards
