Abstract: A wall assembly and method for making the same which consists essentially of a layer of first metallic material and a layer of second metallic material, each layer having one face in a face-to-face contact, either bonded or unbonded relation with a face of the other layer, containing a fusion weld joining two members of the first layer, and fusion welds joining the layer of second material of such member in edge abutting relation to an inlaid insert over a flush insert of second material inset into said first layer so as to provide a relatively smooth surface in the second material of the wall.

Abstract: An improved composite wall construction and method of fabrication is disclosed in which a wall assembly is comprised of a base metal layer and a layer of corrosion resistant material containing an intermediate filler of base metal fusion welded to the original base metal members and to an inlaid insert of base metal at the weld root, and a fusion weld joining the layer of corrosion resistant material to provide a relatively smooth surface in the corrosion resistant layer.

Abstract: An improved composite wall construction and method for fabrication or repair of equipment having layered metals forming a corrosion resistant liner on a structural metal backing which includes fusion welding the abutting ends of the backing metal to an interposed base strip, bridging these ends and welds with an inlay strip of liner material underlying the ends of the liner material, and fusion welding the ends of the liner material to each other and to the inlay strip.
