This study uses high-speed X-ray imaging to capture the dynamics of the friction stir welding process, revealing the formation and filling of cavities during welding.
This study employs high-speed X-ray imaging to capture the process dynamics during FSW in-situ, using a high-intensity X-ray beam to image a 2 mm x 2 mm area at 20,000 frames per second. The friction stir (FS) tool made of H13 tool steel with threads and 3-flats on the probe was used in an aluminum 6061-T6 workpiece. The process parameters employed result in a fully consolidated weldment without any observable sub-surface voids. The density changes captured by the high-intensity X-ray beam show the formation and filling of cavities in the wake of the tool three times per rotation.(c) 2022 Society of Manufacturing Engineers (SME).
