TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Stir welding generates high-quality joints in fabricated structure and is the baseline joining process for most NASA aluminum alloy structures such as cryogenic tanks and lightweight structures. Incorporating ultrasonic vibration to critical stir welding machine components will enable and expand stir welding to other high-strength, high-temperature alloys using solid state joining. This project will scale up proven ultrasonic vibration technology and incorporate it on a NASA stir welding machine for the weld fabrication of extendable liquid rocket engine skirts and other high temperature applications for space structures.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Solid state stir welding of thick-section aluminum, titanium, and high temperature nickel alloy materials is enabled for the improved manufacture of extendable rocket engine nozzle skirt applications, space vehicle primary structure, cryogenic tank structure, and for other fabricated structures for high temperature space craft structural components. Supports welding in space capabilities.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Aerospace and commercial airframe structures, Navy and commercial ship building (Ti and Steel alloys), bridge structures, rail car structure, tank trucks, DOD tracked and wheeled vehicles
