Unless brazing operations are contained within an inert or reducing atmosphere environment (i.e. a vacuum furnace), a flux such as borax is required to prevent oxides from forming while the metal is heated. The flux also serves the purpose of cleaning any contamination left on the brazing surfaces. Flux can be applied in any number of forms including flux paste, liquid, powder or pre-made

What is the optimum atmosphere system for furnace

To produce a well brazed joint, it’s important that your brazing furnace has metal muffle and that the dew point in the furnace’s hot zone is maintained below -40oF. It is also critical to keep the oxygen content in the cooling zones below 15 ppm (parts per million) to help avoid oxidation and discoloration of the stainless steel.

Brazing and Welding Air Products & Chemicals

For sintering and brazing atmospheres in a continuous belt type furnace with open ends, you must follow NFPA 86 Standard for Ovens and Furnaces. Typically, atmospheres containing greater than 4% hydrogen in nitrogen are considered flammable. In fact, any mixed atmosphere—even if it contains less than 4% hydrogen—is considered “indeterminate” and must be treated as if it were flammable.

For most metal joining processes, the role of the furnace atmosphere is to create or maintain a clean surface both on the parent metal and the brazing alloy so that wetting and, hence, bonding can take place. However, this is not the case in one important area the brazing of reactive metals like aluminum. Aluminum is so reactive that, in practice, it is not possible to create an atmosphere
