Resistance spot welding (RSW) is used to overcome the issues in fusion welding of DP-1000 steel such as softening in heat affected zone (HAZ), solidification cracking, high thermal residual stresses and distortion. The main objective of this investigation is to develop the empirical relationships to predict the tensile shear fracture load bearing capability of spot joints for automotive applications. The three factor – three level box-behnken design (3X3-BBD) consisting ofless experiments was chosen for developing the experimental matrix. The lap tensile shear fracture load (LAP-TSFL) and cross tensile shear fracture load (CROSS-TSFL) tests were performed to determine the load bearing capability of spot joints. The empirical relationships of LAP-TSFL and CROSS-TSFL of spot joints were developed using polynomial regression equations incorporating the process parameters in coded form. Analysis of Variance (ANOVA) was executed to check the viability of developed empirical relationships for LAP-TSFL and CROSS-TSFL. The empirical relationship accurately predicted the LAP-TSFL and CROSS-TSFL capability of spot joints with less than 1% error at 95% confidence level.Keywords
