To achieve highly stable long-distance weld connection for ultra-large tank structures, this study conducted research on temperature-controlled friction stir welding (FSW) technology based on the core zone temperature of FSW, and established and released the "Cooperative Regulation Dataset for Long-distance Friction Stir Welding Formability and Performance Based on Constant Welding Temperature Control". This dataset encompasses experimental, machine learning and third-party inspection data, and is divided into four parts: (1) Correlation between surface texture and welding quality: Records surface texture and tensile strength data of long-distance FSW, saved in *.xlsx and *.jpg formats; (2) Influence of assembly errors on temperature and welding quality: Contains process temperature and joint tensile strength data of FSW joints with 8 sets of different gaps and misalignments, saved in *.xlsx and *.tif formats; (3) Dataset on the impact of material deficiency on temperature and weld quality: Includes process temperature and joint tensile strength data from 4 sets of welding tests with varying material deficiencies, saved in *.xlsx and *.tif formats; (4) Real-time temperature measurement and control technology for long-distance FSW processes: Covers on-site certification reports, welding temperature and joint strength volatility reports (*.pdf, *.docx, *.xlsx, *.tif) and tensile curves. 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 includes heavy-duty friction stir welding machines, a self-developed core zone temperature detection system for friction stir welding, and the CMT-5205 electronic universal testing machine. This dataset systematically records the entire process from equipment setup and optimization, correlation between welding temperature, texture and weld quality, to third-party quality evaluation, providing systematic data support for research on temperature-controlled friction stir welding technology for ultra-large structure welds.
