A horizontal vacuum brazing furnace, combining both vacuum and inert gas shielding technologies, is an industrial device specifically designed for high-quality joining of precision metal components (such as aluminum heat exchangers and automotive radiators).

Operation Introduction

Vacuum furnace brazing produces high-quality welds with minimal workpiece deformation. The process involves applying flux to the cleaned and decontaminated workpieces where they are to be welded, followed by the application of solder (powder, granular, or flake form). The other part to be welded is placed on top (also fluxed on the joining surface). The two parts are then positioned and placed in a furnace, heated to the melting point of the solder. The welding process raises the workpiece temperature within the furnace, melting the solder, which has a lower melting point than the workpiece, ultimately achieving the desired weld.

Horizontal Vacuum Nitrogen Brazing Furnace Operation Procedure

Place the cleaned workpiece into the furnace rack → Close the furnace door to evacuate → Turn off the vacuum pump and flush with nitrogen → Heat to the desired temperature, then turn off the heat → Remove the workpiece from the heating chamber to allow for rapid cooling → Cool to approximately 170°C before removing the workpiece.

Industry Applications

The main function of the horizontal vacuum brazing furnace is to provide a high-temperature, clean, high-vacuum environment in which to perform high-temperature degassing and welding on test pieces. It is primarily used for high-temperature vacuum degassing and welding of small and medium-sized precision metal parts. It is particularly suitable for high-temperature vacuum brazing of metal materials such as titanium alloys and stainless steel.
