A large format or large surface area structural component of an aircraft, such as an aircraft fuselage shell, includes a skin panel and a plurality of stiffening elements such as stringers and frames. The skin panel is fabricated from a plurality of individual skin sheets that respectively have different material compositions and different thicknesses, and that are welded together along respective butt weld joints to form the skin panel having different characteristics of strength and the like at different locations. The stiffening structural elements such as stringers and frames may similarly be fabricated by welding together individual material strips respectively having different material compositions and/or thicknesses. Alternatively, an integral shell component can be formed by integrally extruding a skin panel with stringer members integrally formed thereon. With such a fabrication process and resulting structure, there is no need to carry out chemical or mechanical material removal steps, or material addition steps, for providing areas having different skin thicknesses in the resulting structural component. There is also no need to use skin sheets having the largest possible dimensions, but instead a great plurality of small individual skin sheets is joined together in the manner of a patchwork quilt, so as to provide the particular individual characteristics at each location as required in the finished structural component. -1-
