When your brazing needs are more diverse, a combination of convection preheating and radiation brazing could be your answer. The addition of convection preheating to a radiation braze chamber improves the furnaces overall flexibility, enabling manufacturers to braze products of different mass and dimensions without changing the furnaces set point parameters. As pictured above, the preheat chambers uses both convection heating and radiation heating to uniformly preheat the products in a continuous cycle. Once preheated to approx. 540 degrees C (1000 degrees F), the heat exchanger moves into the radiation brazing section and is brought to and held at a uniform temperature to allow the cladding to melt and form a joint. This type of furnace also uses stainless steel convection preheat and radiation muffles.
