Welding effect of vacuum brazing furnace

Vacuum brazing means that the workpiece is heated in a vacuum chamber. It is mainly used for the welding of high-quality products and easily oxidized materials. The vacuum brazing furnace consists of a pressure vessel with a cylindrical side wall and a door whose size and position are designed to close one end of the cylindrical side wall. The workpiece handling system is installed on the pressure vessel door to support metal workpiece for heat treatment or brazing. The workpiece processing system includes a device for turning the workpiece during processing. The vacuum system can be connected to the workpiece so that the pressure inside the workpiece is lower than the atmospheric pressure during brazing.

Brazing in vacuum furnace is a new brazing method without flux in vacuum. Because brazing is in vacuum environment, it can effectively eliminate the harmful influence of air on the workpiece, so it can be successfully brazed without flux. It is mainly used for brazing those hard to braze metals and alloys, such as aluminum alloy, titanium alloy, superalloy, refractory alloy and ceramics. The brazed joint is 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. Vacuum aluminum brazing furnace is mainly composed of vacuum brazing furnace and vacuum system. There are two types of vacuum brazing furnace: Hot fireplace and cold fireplace. The two types of furnaces can be heated by natural gas or electric heating, and can be designed as side loading furnace, bottom loading furnace or top loading furnace (Kang type). The vacuum system can be used in general. The vacuum system mainly includes vacuum unit, vacuum pipeline, vacuum valve, etc. The vacuum unit is usually composed of rotary vane mechanical pump and oil diffusion pump. Only using mechanical pump can get vacuum degree lower than 1.35 × 10-1pa. In order to obtain high vacuum, the oil diffusion pump must be used at the same time. At this time, the vacuum degree of 1.35 × 10-4Pa can be achieved. The gas pressure in the system is measured with a vacuum gauge.
