Assessment of Mechanical Properties of PCGTA Weldments of Inconel 625

Inconel 625, a Nickel based superalloy has outstanding features such as high corrosion resistance and high strength. Inconel 625 is preferred and widely used in aerospace, nuclear and power plant components where they are exposed to elevated temperatures. In this work, an attempt has been made to investigate the weldability, metallurgical and mechanical properties of the PCGTA welded Inconel 625 metals employing ERNiCrMo-3 filler wire. Structure-property relationships of Inconel 625 weldments are discussed in detail.
