This invention relates to integral sheet metal refrigerator evaporator assemblies of the roll-forged type in final form having one section extending in a complete rectangular loop enclosing the freezing compartment and a depending plate section located in the above-freezing compartment. As an intermediate product a pair of evaporator assemblies are formed of two superposed planar sheets forming a composite panel having two L-shaped patterns of stop-weld material interposed between the sheets arranged in invertedly nested fashion for subsequent lancing from the panel with a minimum of scrap material.
