In this thesis, we investigated micro resistance spot welding of dissimilar materials, such as silver-plated copper and copper sheets, which are used in battery packs. The goal was to determine the optimal welding parameters (current, welding time) that ensure reliable and durable joints. Preliminary research identified initial parameters through visual and mechanical testing. Further analysis using the design of experiments method enabled the modeling and optimization of parameters to achieve the highest tensile strength. The results show that currents above 2.2 kA and welding times around 200 ms ensure the highest-quality welds. Surface analysis confirmed a strong correlation between weld strength and optimized parameters.
