摘要

This study analyzes and optimizes the friction stir welding (FSW) process for 5052 aluminum alloy, a lightweight alloy valued for its corrosion resistance and mechanical strength. The research aims to identify optimal FSW parameters that enhance mechanical properties, particularly yield strength, while minimizing weld defects. A systematic experimental approach is employed, incorporating a mathematical model to evaluate the influence of key process parameters and their interactions. The results highlight that the shoulder type is the most critical factor in FSW, with its interaction with rotational speed having a more significant impact than welding speed alone. The optimized parameters lead to substantial improvements in weld quality and mechanical performance. These findings provide actionable recommendations for industrial applications, demonstrating the advantages of FSW in achieving high-performance welds for demanding environments.
