  • Abstract:
  • This paper presents an experimental investigation into the mechanical behavior of friction stir welded (FSW) joints using AA6061 aluminum alloy. The study evaluates the impact of varying process parameters specifically rotational speed and feed rate on the hardness and structural integrity of the welds. Welding was performed using a CNC vertical milling machine at rotational speeds of 1000 RPM and 1500 RPM, with feed rates of 25 mm/min, 30 mm/min, and 35 mm/min. Results indicated that joints produced at 1500 RPM and a 30 mm/min feed rate achieved superior weld integrity, showing a 29% improvement in hardness compared to other tested combinations. These findings emphasize the critical role of parameter optimization in enhancing FSW joint performance for high-strength applications.
