On-line Phased Array Ultrasonic Testing (PAUT) System for Friction Stir Welding (FSW)

Friction Stir Welding (FSW) is a relatively new solid-state welding process, and many industries are now relying on this technique to produce advanced structures. Industries employing this technique include, but are not limited to, aeronautical, motor vehicle, and maritime. As with any welding technique, the quality of a weld must be determined to ascertain reliability and safety. For this reason, a welded structure has to go through a rigorous screening process.
