Abstract

The objective of the present work is to research the dissimilar welding of Duplex Stainless Steel AISI 2205 to Austenitic Stainless Steel AISI 201. Gas tungsten arc welding with identical parameters and procedures was used to a square butt welding with two types as cooling rate (cooling by carbon steel, copper, and copper with water cooled), and welding of speed (1.5 mm s 1 , 2.5 mm s 1 and 3.5 mm s 1 ). Metallographic, hardness, tensile strength was examined for all specimens. The results of this research reveal that the optimum properties of the specimen were welded with parameter as cooling by copper with water cooled and welding speed 3.5 mm s 1 have shortest of dendrite length (76.44 m), lowest of the width of face welded (6.04 mm), maximum hardness and tensile strength.
