Welding of duplex stainless steels gains interest, significantly due to their increasing application fields. The problems come into question about the weldments of these steels improper distribution of important phases like delta-ferrite, austenite and other intermetallics. In order to maintain sufficient corrosion and mechanical properties in welding, the optimum delta-ferrite phase ratios must be kept within approximately %35-65 by volume. In this study; thicknesses of 3mm S32205 (2205) duplex stainless steel plates were TIG welded by pure argon shielding gas. The effects of various welding cooling circumstances on microstructural developments were examined.
