To reveal the forming and property evolution regularities and the weak points in microstructure and properties of thick/medium plate weld joints during friction stir welding (FSW) of high-strength aluminum alloys, this study constructed the "Dataset on Microstructure Evolution and Weld Joint Properties of High-Strength Aluminum Alloy Thick/Medium Plates During Friction Stir Welding". This dataset covers three core types of data: mechanical properties, welding process temperature, and finite element simulation results. Friction stir welding weld specimens with thicknesses of 6 mm, 12 mm, and 18 mm were obtained using different process parameters. Standard tensile specimens and layered tensile specimens were prepared via wire electrical discharge machining (WEDM), and tensile tests were conducted using a CMT-5205 electronic universal testing machine. Welding process temperature was measured by embedding thermocouples inside the workpieces. The temperature field during aluminum alloy friction stir welding was simulated via finite element analysis using Abaqus software. Data collection was carried out from January 2021 to April 2025 at the School of Mechanical and Electrical Engineering and the Light Alloy Research Institute of Central South University. The main equipment used includes heavy-duty friction stir welding machines, the High-Performance Computing Center of Central South University, and the CMT-5205 electronic universal testing machine. This dataset comprehensively records welding process parameters, welding process temperature, mechanical responses, and microstructure characteristics, providing systematic data support for research on the regulation of weld joint properties of high-strength aluminum alloy thick/medium plates.
