Abstract
A manufacturing system includes a tension-wound system having a feedstock system and a shape fixture. The tension-wound system is configured to feed a feedstock from the feedstock system and to wind the feedstock under tension in successive layers around the shape fixture to allow the feedstock to form a component having a shape represented by the shape fixture. The manufacturing system includes a solid-state joining tool configured to additively join the successive layers of the feedstock. In a spiral tension-winding process, with a continuously-fed strip of aluminum feedstock around a piece of tooling, the feedstock can be friction stir welded and additively joined in successive layers to produce a large, near-net structure.
