Resistance spot welding is one of the most common welding techniques used in the automotive and aviation industries. In the present research, the effect of resistance spot welding parameters such as, holding time, squeeze time, welding current, force applied, and welding time will be examined using Simufact Welding 2020, a welding simulation application. The impact of these parameters on the strength of the weld in metal sheets are studied. Each parameter was studied separately by changing one parameter within the range values and other parameters as constant values. It was found that the best region for the following spot-welding parameters is, from 0.9 s to 0.95 for squeeze time, 6.5 kA to 7.5 kA for welding current, 0.15s to 0.4s welding time, 30 ms for holding time, and 3.2 KN to 3.4 KN for electrode force. These parameter ranges are best to provide a spot weld with the highest yield stress.
