Fluxless aluminum vacuum brazing is a sophisticated process that produces the highest quality joints in aluminum components. Complying with the stringent standards of AWS C3.7 and AMS-2678, our vacuum brazing process offers unparalleled precision and control
How Vacuum Brazing Works
Our state-of-the-art vacuum brazing process involves:
Pre-cleaning:In preparation for the vacuum brazing process, all components are chemically cleaned to remove all surface contaminants and oxides, which can inhibit the process. Assembly and Fixturing: Chemically cleaned components are assembled with brazing alloy placed between all components. The assemblies are then fixtured to ensure uniform contact and pressure on all mating surfaces. Heating in a Vacuum Chamber: Assembled and fixtured components placed in a vacuum chamber, where they are heated to approximately 1100°F for brazing. The vacuum environment eliminates oxygen, preventing oxidation and ensuring joint purity. Process Monitoring and Ramp Down: During the brazing process, environmental variables such as oven temperature, oven atmosphere and component temperature are monitored. Once the component temperature reaches the desired brazing temperature for the specified duration, the oven temperature and atmosphere are gradually reduced to ambient conditions, allowing the part to be handled and further processed.
