![]() The softened material flows around the tool through extensive plastic deformation and is consolidated behind the tool to form a solid-state continuous joint. A specially designed tool rotates and traverses along the joint line, creating frictional heating that softens a column of material underneath the tool. ![]() DebRoy, Science, v257 pp497-502, 1992įriction stir welding process Friction Stir Welding (FSW) is a new, novel solid-state joining process. Growth of welding processes after the invention of electric arc Future developments in welding processes are expected through fundamental understanding of physical processes. ![]() Application of nanoscience and technology for materials joining. Significant advances have been made in the last two decades related to welding processes Enhanced application of laser for manufacturing Friction Stir Welding Hybrid Welding Keyhole Plasma Welding Magnetic Pulse Welding Ultrasonic Welding Transient Liquid Phase Joining Future Directions Processes such as FSW, Hybrid and others will be used extensively in energy, transportation and ship building etc. A David and Zhili Feng Materials Joining Group Metals and Ceramics Division Oak Ridge, TN 9th Materials Day in Graz In Honor of Professor H. “ Prediction is very difficult – especially if it is about the future.” – Niels Bohrįriction Stir Welding of Advanced Materials: Challenges D0000710 S. ![]()
