Abstract: An improvement in process for reinforcing a structure against fatigue failure and the resulting structure are set forth. The structure comprises joined weldable structural portions having adjoining surfaces which meet at a junction and diverge therefrom to form a gap between each other. A brace with weldable terminal feet spans the gap. Each such foot rests against a structural portion, and the brace is plug-welded to at least one of the structural portions through a hole in a foot, or a hole in a structural portion or holes in each such portion where they interface. The invention is especially efficient for bracing an air chamber bracket that is designed for automotive use. A preferred rigid structure has the feet welded at both ends.
