WebNASA's Marshall Space Flight Center has developed a cost-effective pin tool for use in self-reacting friction stir welding (SR-FSW), making the SR-FSW process significantly more robust and cost-effective. The IFR Tool mitigates the internal friction that occurs between the weld pin and crown-shoulder during a SR-FSW weld. WebFriction Pull Plug Welding (FPPW) is the process necessary to plug the hole that is left behind as a friction stir weld (FSW) joint is completed and the pin tool of the welder …
