In this present work, an attempt was made on optimising the Resistance Spot Welding (RSW) process parameters for joiningtwo dissimilar combinations of AISI 304 and AISI 1020 grade steel with each other. Experiments were conducted by varyingthe three weld process parameters such as welding current, pressure and welding time. The integrity of the weld joints wasevaluated mechanically and metallurgically. Tensile shear fracture, nugget diameter, and hardness properties were examined.
Macrostructure, Microstructure, and Scanning Electron Microscopy (SEM) analysis were carried out on the tested samplesto validate the type of fracture occurred. Maximum nugget diameter and maximum tensile fracture of 6.666 mm and 10.5 kNwere achieved respectively. The experimental results confirmed the validity of the used Response Surface Methodology appliedfor optimising the welding process parameter in the RSW process. The Response Surface Methodology (RSM) results showthat the weld current is the most significant factor for Tensile Shear Fracture Load (TSFL) and nugget diameter, followed byweld pressure and time.
