Dissimilar joining of commercially pure aluminum and AISI 304 stainless steel was carried out using electron beam welding machine (12 kW) under three different parameters. The aim of this work is to evaluate the quality of weld joint through microstructural analysis, hardness measurement, and porosity calculations. Microstructural analysis as well as quantitative elemental analyses demonstrated increased thickness of the weld zone and interlayer by increasing heat input. Scanning electron microscopy together with area mapping has been done to analyze the microstructure of the samples. The optimized process parameters mainly show the variation of beam current and scan speed, while keeping beam voltage (55 kV) and beam offset (0.7 mm in Al side) constant. Mainly AlFe and AlFe3 are the intermetallic phases formed during joining.
