Vacuum brazing, refers to the workpiece heating in vacuum chamber, mainly used for welding requirements of high-quality products and easy oxidation material. Vacuum brazing furnace includes a pressure vessel having a cylindrical side wall and door, door the position and size of the designed end can be closed cylindrical side wall. Workpiece processing system is installed in the pressure container door, for supporting the metal workpiece heat treatment or brazing. Workpiece processing system includes a device to make the workpiece rotation during processing. The vacuum system can be connected to the workpiece, the workpiece internal stress in brazing process was lower than the atmospheric pressure.
