Resistance spot welding (RSW) is vastly used in automobile industries to cut weight and lower the cost. It is necessary to improve ultimate strength of spot-welded joints for safety of automotive. The Spot weld joints provide localized connection which leads to high stress concentration in the joined plates. Also due to improper design excessive stresses and premature failure occurs in joined plates. A designer should have concentration on the strength of component by introducing the changes in its geometry and weld patterns that will reduce the vibration and noise of the structural models. Also increases the strength of the structures. The optimum design of geometry and weld patterns will give optimal performance i.e. good strength to the composed structures. The aim of this study is to find out the effect of spot weld parameters on the strength of spot weld. The effect factors of multiple spot-welded joints strength are analyzed including spot weld arrangement, distance between two spot welds, spot weld diameter and thickness based on finite element analysis (FEA) and experimental results. The study shows that weld diameter and thickness are primary factors affecting the strength of the joints for a given material. On the basis of effect factor analysis the optimized parameters are also discussed to improve the strength of structure.
