Description
Summary:In the study, the effect of welding time on resistance spot weldability of aluminum 5052-H32 alloy was analyzed through simulation and experiments. The resistance spot weldability was evaluated by measuring the tensile shear strength, nugget size, and hardness of welds with variations in the welding time. The simulated results of parameters such as tensile shear strength and nugget size obtained using the SORPAS program were compared with the experimental results. Furthermore, a simulation was performed to calculate the temperature inside the weld nugget based on the distance from the center of the nugget. Hence, an optimum welding time to retain the required weld strength of the aluminum 5052-H32 alloy was obtained.
