Abstract
In the present study, electron beam welding of solution treated Inconel 718 alloy (3Â mm thickness) was carried out under varied parameters (50, 60 and 70 kV voltage: 64, 60, and 57.2Â mA current: and 1600, 1800 and 2000Â mm/min scan speed) in vacuum (1.6*10-5 mb). The effect of process parameters on microstructure, mechanical properties and electrochemical properties was meticulously studied. It was observed that the shape and size of weld zone and heat affected zone (HAZ) varies with process parameters. The detailed corrosion behaviour shows that there is no deterioration of corrosion resistance property in a 3.56 wt. % NaCl solution due to electron beam welding.
