| Abstract Scope |
Tool design in linear friction stir welding has been largely Edisonian with organizations having favorite tools and features that have been used without clear data showing cause and effect. Previous studies evaluating features have elucidated certain trends with respect to reducing reactionary forces on the tools, although most of these studies focused on fixed tool diameters with few variations based on the complexity associated with machining or grinding new tool geometries. The present work focuses on FSW tools that have been produced using direct laser sintering to enable rapid evaluation of numerous tool features and designs. Tools were produced showing the effects of variation in shoulder convexity, shoulder features, probe features and probe geometry. Analysis of how each feature influences the transverse and axial forces are presented, as a means of demonstrating low-force tool designs. |
