When scaling friction stir welding to production, fixturing is often an undervalued or under-engineered part of the design effort, despite its criticality in ensuring proper weld containment and joint fit-up. Reports of weld forces are typically focused on the process forces internal to the weld plate rather than the forces required for fixturing. These fixturing forces were quantified in our previous work. The separation forces on the retreating side of the pin tool were found to be approximately equal to the path normal loads exerted by the tool. The object of this study was to expand on this previous work, with new tools, to measure the fixture separation forces from the advancing side of the pin tool using improved fixturing. When combined with the previous work on the retreating side forces, this study provides a more complete picture of the forces that are required for fixturing friction stir welds.
