    The brazing method in the vacuum furnace is a relatively new brazing method that does not apply flux under vacuum conditions. Because the brazing place is in a vacuum environment, the harmful effects of air on the workpiece can be effectively eliminated, so the brazing can be successfully carried out without applying flux. Vacuum brazing furnaces are mainly used for brazing metals and alloys that are difficult to braze, such as aluminum alloys, titanium alloys, high temperature alloys, refractory alloys and ceramics. The brazed joints are bright and compact, with good mechanical properties and corrosion resistance. Vacuum brazing equipment is generally not used for needle welding of carbon steel and low alloy steel.

    The brazing equipment in the vacuum furnace is mainly composed of a vacuum brazing furnace and a vacuum system. There are roughly two types of vacuum brazing furnaces: hot fireplaces and cold fireplaces. The two types of furnaces can be heated by natural gas or electric heating, and can be designed as side-mounted furnace, bottom-mounted furnace or top-mounted furnace (Kang type) structure, and the vacuum system can be universal.

    Brazing in a vacuum furnace is brazing in a furnace or brazing chamber where air is drawn. It is especially suitable for brazing large and continuous joints. It is also suitable for connecting some special metals, including titanium, zirconium, niobium, Molybdenum and tantalum have a wide range of applications.
