Summary:Superalloys are deemed as the most predominant material due to their exceptional mechanical characteristics such as better strength and corrosion resistance which are extensively adopted in various engineering applications like aircraft gas turbines. Nickel alloys are exhibiting better resistance to heat which makes the material to use in higher temperature applications ranges from cryogenic to 1400 °C. Inconel 718 is one of the nickel-based superalloys, well suited for various engineering applications. Laser welding is one of the advanced methods used for joining metals that produces better weldments with lesser defects. In this present investigational analysis, an endeavour has been made to analyse the mechanical properties of laser welded Inconel 718 alloy thin sheets. The tensile strength and hardness of the weldments have been investigated and evaluated for optimized weldments. It is perceived from the investigation that the weldments are having better mechanical properties such as tensile strength and hardness.
