Abstract
A structure and a method of making a burner box by providing a U-shaped body with end members. The end members each rest on an end of the body and of the U-shape body. The ends are welded to the end members to the U-shaped body by a tungsten arc gas welding process whereby the end members are welded to the U-shape body and the edges are catalyzed in the weld. The end members overlaps the U-shape body by about half the thickness of the body to provide a filler material for the weld. A tab is integrally attached to each side of each of the end members. The tab rests on flanges and are catalyzed in the weld.
