DIGF-CORD-06257 - Manufacturing Feasibility of Double-Sided Web Stiffened Wing Structures Using Additive Friction Stir Deposition Process of AA7075 Alloy

Solid-state deposition process can deposit fully dense material, i.e., no melting, no porosity, hot-cracking. The deposits also exhibit low residual stress and distortion. Additive Friction Stir Deposition (AFSD), also commercially known as MELD, is a typical solid-state deposition technology that is emerging as an alternative to existing additive manufacturing processes, e.g., Directed Energy Deposition (DED) – Arc or Laser, also referred as wire-arc additive manufacturing (WAAM) and laser metal deposition (LMD) respectively, for directly fabricating or remanufacturing large-scale components.

The AFRC are looking to further investigate and evaluate the efficacy of AFSD technology using Aluminium for commercial application and initial evaluation of Titanium alloy applications.
