Study on welding procedure and joint properties of Inconel 617 and 022Cr19Ni10
A new welding procedure has been developed for Inconel 617 nickel based alloy and O22Cr19Ni10 stainless steel dissimilar metal weld joint,the welding wire is selected as AWS ERNi-CrCoMo-1,and M-GT AW is used to achieve reliable welding between Inconel 617 and O22Cr19Ni10.Mechanical properties and macro and micro tests were conducted and the lab results showed that the weld structure was austenite mixed with a small amount of ferrite,the tensile strength of the weld joint was 765MPa and 769MPa,the hardness value of the weld is similar to that of Inconel 617 base metal,and higher than that of O22Cr19Ni10 base metal.The properties of the joint can meet the engineering requirements.
