Friction Stir Welding of Additively Manufactured Aluminum Alloys

Todd Evans (Vanderbilt University) discusses friction stir welding of additively manufactured aluminum alloys. Recognizing the lack of published information for materials produced using additive manufacturing, Vanderbilt’s Welding Automation Laboratory (VUWAL) and NASA teamed up to research the weldability of various aluminum alloys used in a wide range of aeronautical applications.
