1. A metallic structure, comprising:
a metallic sheet, comprising a metallic-sheet first surface and a metallic-sheet second surface, wherein the metallic-sheet first surface and the metallic-sheet second surface face in opposite directions;
a metallic doubler, extending from a portion of the metallic-sheet first surface;
a first junction between the portion of the metallic-sheet first surface and the metallic doubler;
a metallic article, additively manufactured on or welded to a portion of the metallic-sheet second surface; and
a second junction between the portion of the metallic-sheet second surface and the metallic article;
wherein:
the first junction has a first-junction area and a first-junction boundary that circumscribes and defines the first-junction area;
the second junction has a second-junction area and a second-junction boundary that circumscribes and defines the second-junction area;
when viewed at any point along the second-junction boundary in a direction, perpendicular to the metallic-sheet first surface, the second-junction boundary does not extend outside of the first-junction boundary;
in a plane, intersecting the metallic doubler and perpendicular to the metallic-sheet first surface, the metallic doubler has at least a first doubler thickness and a second doubler thickness, which is less than the first doubler thickness;
in the plane, intersecting the metallic doubler and perpendicular to the metallic-sheet first surface, the metallic article has at least a first article thickness and a second article thickness, which is less than the first article thickness; and
in the plane, intersecting the metallic doubler and perpendicular to the metallic-sheet first surface, the first article thickness is disposed over the first doubler thickness and the second article thickness is disposed over the second doubler thickness.
