Optimization of ultimate tensile strength of welded Inconel 625 and duplex 2205

Journal of Mechanical Engineering and Sciences, 2021
The ultimate strength is an important property of any material for the manufacturing of components. This paper utilized the laser beam welding (LBW), due to its smaller dimension, which produces lesser distortion and process velocity is higher.
