As a member of the National Science Foundation's Center for Friction Stir Processing, the research and development efforts of the Advanced Joining and Processing Lab are driving advancement in Friction Stir Welding (FSW). Advanced Joining and Processing Lab focuses on Friction Stir Welding and its variations: Friction Stir Spot Welding and Friction Stir Processing.
FSW is an automated solid state joining process that offers numerous benefits in joining metals and thermoplastics including minimizing or eliminating defects typically encountered in fusion welding, such as excessive weld distortion, weld cracking and lower mechanical properties.
Other benefits of FSW over established mechanical joining methods include improved joint strength, reduced manufacturing time, reduced complexity of the manufacturing process, reduced parts count and weight, and an ability to work with previously unweldable materials. This technology is increasingly replacing rivets and fusion welding on
many aircraft structures.
The Advanced Joining and Processing Laboratory was developed and is used in part by the NIAR/Industry/State (NIS) program and the Federal Aviation Administration.
