Experiment and Simulation of Influence of Welding Parameters on Temperature in Friction Stir Welding

摘要

Temperature distribution is the foundation to study friction stir welding technique,influence of welding parameters on temperature was studied through experiment measurement on AA2024-T4 aluminum alloy plates.An instantaneous relative linear velocity based heat source was utilized to build the FEM model of friction stir welding process,good agreement was observed between the measured and simulated thermal profiles.FEM model was also utilized to study effect of welding parameters on temperature distribution.
