Investigation on Dissimilar Metal Welds by Resistance Spot Welding Process

In the present scenario welding of dissimilar metals is very important because one metal cannot gives optimum chemical, physical and mechanical properties required for an application. Like Al-Steel or Mg-Al welding for reducing the weight of the transportation vehicles such as train, automobile, and ship, high alloy material-low alloy steel or stainless steel- low carbon steel for strength and corrosion resistance, Al-Cu for electronic components. So many researches have been carried out on joining of Fe-Al by RSW using different elements as interlayer but optimization of cladding ratio for transition material is not done. Here in this paper condition for optimum performance is determined in the terms of influence of parameters on the tensile shear strength of the weld, optimize the process parameters without the Silver interlayer, optimize the process parameters with the Silver interlayer, and investigate the mode of failure of these welds.
