Introduction to Furnace Brazing - Air Products & Chemicals

The disadvantages of furnace brazing have to do mainly with furnace issues, e.g., the cost of equipment (versus flame brazing), higher power consumption, and furnace maintenance requirements. In addition, somewhat more attention has to be paid to joint design because the brazing takes place in the furnace chamber, and is not easily observable.
