Troubleshooting Atmospheres for Furnace Brazing
Brazing furnace atmospheres perform a critical role in the final quality and metallurgical properties of the brazed component. Typically, exothermic, dissociated ammonia, or nitrogen/hydrogen atmospheres are used for brazing mild steel, alloy steel, and stainless-steel parts. Atmosphere composition, flow rates, pressures, and dew point are some of the key variables influencing final part quality, which must be controlled. Common problems include oxidation, flashing, inadequate braze flow, decarburization, and carbon pickup.
This webinar reviews years of collective field experience with nitrogen/hydrogen-based atmosphere systems. It will help heat treaters identify problems and apply the appropriate corrective action.
