Abstract
Abstract A method for controlling the flow of filler alloy used in the brazing of metals such as stainless steel. The method consists of applying on the surface of the metal a layer of metal which acts as a barrier to the filler alloy, thereby confining the alloy to the desired area to be brazed and thus preventing its flow over undesired areas of the surface of the metal. The flow control metal may, for example, be applied to the surface by scribing, plating or vapor-deposition depending on the type of flow control metal utilized.
