ABSTRACT:
An autogenously welded structure is provided that includes a first face sheet, a plurality of individual stiffener elements, and a second face sheet. The stiffener elements each have a first edge disposed against the first face sheet and an opposed second edge. Each stiffener element has a central portion extending between the opposed edges. The central portion is disposed at an angle to the first face sheet. The stiffener elements include at least some stiffener elements that are disposed at an angle to at least some of the other stiffener elements. The second face sheet is disposed against the second edges of the stiffener elements and the first and second face sheets are autogenously welded to the edges of the stiffener elements.
