The effect of welding parameters on weld zone characteristics of electron beam welded aluminium and AISI 304 stainless steel has been carried out. The aim of this work is to evaluate the quality of dissimilar weld joint between aluminium and stainless steel (SS) plates using a 12 kW Electron Beam Welding machine, through microstructural analysis, hardness, tensile and surface properties. Microstructural analysis as well as quantitative elemental analyses demonstrated increased involvement of iron with aluminium in the fusion zone by increasing heat input. Scanning electron microscopy has been done to analyse the microstructure of the samples. Mechanical properties were studied using tensile test and nano-indentation technique. The optimised 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.
