OVERVIEW

The Advanced Joining and Processing Laboratory provides research driven by friction stir welding (FSW) and friction stir processing (FSP), both patented in 1991 by The Welding Institute. This revolutionary solid-state joining technology is increasingly replacing rivets and fusion welding on many aircraft structures. Over the last decade, FSW has grown explosively in research, development and application, which means NIAR’s FSW research efforts are crucial to staying ahead of the curve.

Since its initial development, the FSW process has shown itself to have a number of benefits over established mechanical joining methods—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, such as high-strength 7xxx series aluminum and metal-matrix composites. For aircraft structures, FSW offers significant design and manufacturing benefits over current joining methods.

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. The lab is also recognized as a Center for Friction Stir Processing by the National Science Foundation. The Advanced Joining & Processing Lab provides research and testing for one of the most rapidly advancing aviation technologies, helping NIAR maintain its reputation as a premier aviation research facility.
