| Summary: | ABSTRACT The investigation of material flow in friction stir welding (FSW) is regarded as essential for enhancing the understanding of the processes that influence the quality and structural integrity of welded joints. Critical factors such as microstructural refinement and the resultant mechanical properties of the weld are governed by material flow, which ultimately determines the performance and durability of the joint. This knowledge is deemed crucial for the identification and mitigation of potential defects that can compromise weld strength. Furthermore, a comprehensive understanding of material flow facilitates the optimization of tool design and welding parameters, thereby improving the efficiency and applicability of FSW across various manufacturing contexts. In this review, material flow during FSW is systematically investigated, beginning with an overview of the methodologies employed to study this phenomenon. Subsequently, the dynamics of material flow during FSW are examined, including the interactions between the tool and the workpieces, the filling cavity process, defect formation, and the various parameters influencing material flow. Finally, material flow in novel variants of FSW, specifically Bobbin Tool Friction Stir Welding and Stationary shoulder Friction Stir Welding, is discussed, highlighting their unique characteristics and implications for future research and application. |
