Abstract

Undergraduate Design: Design of a Prototype Reusable Stir Friction Welding ToolAt XXX________, undergraduate research is encouraged. The college has worked diligently atdeveloping funding and recognition programs that enhance research opportunities at theundergraduate level. The benefits of undergraduate research are many. This paper will discussthe design of a reusable Stir Friction Welding (SFW) tool performed by two undergraduateMechanical Engineering Technology students (sophomores)SFW uses a solid-state joining process, which heats the material by using friction under pressureto heat the material just under its melting point. This heat is used to form the weld along thejoint of the two butted substances. This process allows for many advantages over traditional arcwelding with electricity.The design group consisted of two students that were part of a larger group of studentsconducting research in the area of SFW. SFW tools are not standardized. They cannot bepurchased off-the-shelf from an industrial supplier. SFW tools are quite often damaged orfractured during their use, especially during research. Common SFW tools that are generallymanufactured are tools that include the probe and shoulder as one solid piece. This is a majordisadvantage when the welding tip breaks. It may take days if not weeks to have another SFWtool made or repaired. This research project will involve researching and designing a prototypeSFW tool that will allow the user to quickly change the welding tip so that it may take minutesinstead of days to continue welding. The outcome of this project is to design a Stir FrictionWelding tool that can be reusable with minimal down-time.
