The process involves using various types of furnaces using either vacuum or gaseous atmosphere. In the process, the filler metal is distributed in the joint by means of capillary action.
Various materials can be joined by using furnace brazing machine. Furnace brazing is more suitable for value added components. It is advisable to avoid high vapour pressure elements like; zinc, lead, cadmium, etc. in vacuum brazing.
Machine Details
The furnace of the machine is constructed on the basis of either batch type or continuous operation. Batch operation makes use of retort type of furnace for hydrogen brazing. Vacuum chambers are used for vacuum brazing. The most widely used fillers for furnace brazing are based on silver, copper, nickel and gold.
Advantage of Furnace Brazing Machine
- The process reduces the use of fluxes.
- There is no need of post-braze cleaning in the machine.
There are several areas where the furnace brazing machine finds application. Some of its popular uses include :
- Joining electrical & electronics components
- Brazing aeroengine components
- Joining nuclear & gas turbine power generation components
- Marine applications
- Engineering applications
