The necessarily high preheating results in the underlying metal becoming more or less the oxygen in the air and in consequence union of it with the molten metal. If such oiidation occurs, the two metals will not weld over their entire contacting surfaces, but are onl sporadically stuck together and will there ore again separate during use.-
That is the more ikely often to occur when two" metal elements which are so attached later become subjected to an operation like rolling, tension or cutting.
I have moreover discovered that the quality of the fluid-applied metal suffered a reciably during the practice of previous y known methods owing to its exposure to atmospheric oxygen while pouredor deposited dropwise upon the base and thereby 50:.

The process as specified in claim 1, in which the preheating of'the metabbase progresses under the complete protection of the reducing gases until all of its surface which is to be' covered with molten metal just reaches fusion temperature while preventing oxidation by exclusion of air.
3. The process according to claim 1, in which molten metal is enveloped in a stream of reducing gas to accomplish its liquefaction and thereafter likewise enveloped by said reducing gas stream during its application to the base metal.
