Abstract : The research paper focuses on the feasibility of using friction stir welding (FSW) to join aluminum (Al6063) and pure copper strips to produce lightweight and cost-effective electrical and structural components. The study used a horizontal axis FSW process on a lathe machine and assessed the impact of tool pin offset and tool rpm on the joint's tensile strength, ductility, and toughness. It was found that an optimized tool offset of 10% towards Al6063 side resulted in an enhanced intermixing phenomenon, which led to a maximum tensile strength of 211.9 MPA, representing 92% of the base Al6063 plate's strength. Scanning electron microscopy (SEM) was used to analyze the fracture behavior of the specimen, while Electronic dispersion X-ray (EDX) was utilized to assess the mixing of Al6063 and Cu on the fractured surface. Keywords - Horizontal Axis FSW (HAFSW), Tensile Strength, Toughness, SEM, Electronic Dispersion X-ray (EDX)
