DIP BRAZING (DB) is one of the oldest brazing processes. The materials to be joined are immersed in a hot liquid, which is either a molten flux or a molten filler metal that usually contains a layer of flux to prevent oxidation. Dip brazing is primarily used because of its ability to uniformly heat parts that have a wide range of thicknesses.
The Process is simple when compared with modem, complex brazing equipment and
processes.
The drawback of the process is that it coats everything with flux or braze alloy;
flux can be corrosive to fixtures and surrounding metal structures and equipment. Even when compared with more modern heating methods, the speed of immersion heating is hard to match and dip brazing, therefore, continues to be a common process
