Abstract
A steam chamber has enhanced planarity of its cooking surface, and a method for making the same via friction welding is provided. An array of stays within the steam chamber are friction welded to the undersurface of the upper plate, opposite the cooking surface, thus minimizing the heat affected zone and distortion of the cooking surface as compared, for example, to arc welding. A lower plate includes an array of holes sized and configured to be engaged by the array of stays, and is then welded to the array of stays via plug welds or rosette welds at the hole/stay junction. The resulting steam chamber preserves a high level of planarity in the cooking surface, while allowing the use of a relatively thin top plate for thermal and cooking efficiency.
