Abstract
An increasing demand for vehicle body frame is require the combination of dissimilar metals with various thicknesses to reduce the weight of body. The resistance spot welding of dissimilar metal properties like physical, chemical and mechanical are more challenging. The purpose of present work is to understand the effects of weld process parameters to weld strength and weld quality. Experiments are carried out using the factorial design on Mild steel (MS) and Austenitic stainless steel (ASS 304) to determine weld strength and weld quality. The effect of weld parameters such as weld time, weld current, weld force on weld strength is check. A novel empirical relationship is developed using factorial regression method and ANOVA to validate obtained results. The characterized the weld nugget strength, microstructure, micro hardness and behaviors of parameters on responses. The predicted weld strength from the empirical equation is compared with experimental results. The findings of this research work are useful to understand the change in weld characteristics and properties to obtain better weld joints quality.
