Quality strongly depends on good mechanical properties of any manufacturing material. Similarly, quality Tungsten Inert Gas (TIG) welding Duplex Stainless Steel (DSS) like percentage elongation, ultimate tensile strength etc. Better Percentage Elongation (PE) is produced using proper parameters and their values at the time TIG welding. In this study, has been done ASTM/UNS 2205 duplex stainless...
