Abstract: A rigid panel and a method of making the same, the panel being comprised of a relatively thin gauge sheet of metal and at least one rigid, stiffening member welded to the rear face of the metal sheet. The stiffening member is welded to the sheet by depositing weld metal in spaced apart openings provided in the stiffening member, the openings being located along the bottom of a longitudinally extending groove provided in the stiffner. Opposed side walls of the groove diverge outwardly from the bottom thereof to the surface of the stiffener remote from the metal sheet to provide the groove with a relatively wide dimension at the remote surface, and a relatively narrow dimension at the bottom of the groove and adjacent the metal sheet.
