ABSTRACT:
An improved wall construction and method of fabrication is disclosed in which a wall assembly is comprised of a base metal layer of mild steel with a bonded intermediate layer of copper and a bonded layer of corrosion resistant material containing a fusion weld joining the steel base metal members with the root of the fusion weld abutting an inlaid insert of the corrosion resistant material, a fusion weld joining the layer of corrosion resistant material of the members to each other and to the inlaid insert of corrosion resistant material to provide a relatively smooth surface in the corrosion resistant layer, with the intermediate copper layer removed from the weld areas.
