SIMUWU high-temperature vacuum brazing furnaces

---

Copper and stainless steel nickel-based vacuum brazing process is a reliable welding method for copper and stainless steel parts. It needs to be filled with nickel-based solder in the gap between the copper parts and stainless steel parts to be welded, the gap is controlled between 0.02 ~ 0.1mm, the vacuum degree is within 0.05Pa, and the temperature is 980 ~ 1050 ° C, continuously for 10-60min, and then in the Cool the weldment with the furnace to complete the welding of copper and stainless steel. This copper and stainless steel nickel-based vacuum brazing process can be used for mass production of copper and stainless steel weldments. The weldments can work safely in the temperature environment of -269°C to 1000°C, without cracking or remelting, and the quality of the weld Dense and clean, the helium leak detection rate can reach 5.0*10E-10Pa*m³/s. Due to the good toughness of silver-copper solder, this process is especially suitable for working environments with high and low temperature shocks.

SIMUWU high-temperature vacuum brazing furnace is mainly suitable for vacuum brazing of metal materials, ceramics, stainless steel, high-temperature alloys, refractory metals, non-metals and each other.

High-temperature vacuum brazing furnaces are widely used in inorganic materials (such as ceramic seals, zirconia, zinc oxide, aluminum dioxide, etc.) Materials with cleanliness requirements are subjected to vacuum heat treatment. At the same time, it is suitable for trial batch production in colleges and scientific research units.

Advantages of vacuum brazing:

1.During the entire vacuum brazing process, the parts to be brazed are under vacuum conditions, and there will be no oxidation, carburization, decarburization, pollution and deterioration.

2.When using a vacuum brazing furnace for vacuum brazing, the overall heating of the parts is uniform, the thermal stress is small, and the deformation can be controlled to a minimum, which is especially suitable for brazing of precision products.

3.The low pressure around the base metal and solder can eliminate the volatile gases and impurities released by the metal at the vacuum brazing temperature, and improve the performance of the base metal.

4.Because no flux is used, there will be no defects such as pores and inclusions, which can save the process of cleaning residual flux after brazing, save time, improve working conditions, and have no pollution to the environment.

5.The high-temperature vacuum brazing furnace can complete the heat treatment process of the parts in the vacuum brazing process at the same time, select the appropriate vacuum brazing process parameters, and arrange the vacuum brazing as the final process, so as to obtain brazing performance that meets the design requirements. welding head.

6.Multiple adjacent brazing seams can be brazed at one time, or multiple components can be brazed in the same furnace according to the capacity of the vacuum furnace to improve the efficiency of vacuum brazing.

7.There are many types of metals that can be brazed in the vacuum brazing furnace, especially suitable for brazing aluminum and aluminum alloys, titanium and titanium alloys, stainless steel, high-temperature alloys, etc. It is also suitable for brazing of the same or dissimilar metals such as titanium, zirconium, niobium molybdenum, tungsten, and tantalum. It is also suitable for composite materials, ceramics, graphite, glass, diamond and other materials.

8.SIMUWU high-temperature vacuum brazing furnace has broadened the way of product design. It can be used for parts with narrow grooves, extremely small transition tables, blind holes, closed containers, and components with complex shapes, without considering the problems caused by brazing flux, etc. Corrosion, cleaning, damage and other issues.
