Compared with traditional brazing furnaces, electric heating vacuum brazing furnaces have significant differences in multiple aspects, mainly reflected in the working environment, welding quality, material applicability, production cost, and level of intelligence. Here is a detailed comparison:

1. Working environment

Electric heating vacuum brazing furnace: brazing is carried out in a high vacuum environment, which can effectively prevent metal oxidation and avoid the impact of oxidation products on welding quality.

Traditional brazing furnace: brazing is usually carried out in atmospheric environment or protective atmosphere (such as argon), which cannot completely avoid the occurrence of oxidation reaction.

2. Welding quality

Electric heating vacuum brazing furnace: Due to the presence of vacuum environment, the quality of welded joints is high, with few defects such as pores and cracks, and excellent welding strength and corrosion resistance.

Traditional brazing furnace: Welding quality is greatly affected by environmental factors, and defects such as oxidation and porosity are prone to occur. Welding strength and corrosion resistance are relatively poor.

3. Material Applicability

Electric heating vacuum brazing furnace: suitable for various metal materials, including aluminum, aluminum alloy, copper, copper alloy, stainless steel, alloy steel, titanium alloy, etc., and can even achieve welding between dissimilar materials.

Traditional brazing furnace: The applicability of materials is relatively limited, and some easily oxidizable or highly reactive metals are easily affected by environmental factors during the welding process, leading to a decrease in welding quality.

4. Production cost

Electric heating vacuum brazing furnace: Although the equipment investment cost is high, due to the high welding quality and high yield, the loss of waste caused by welding defects is reduced. At the same time, the internal structure and fixtures of the furnace are subjected to less corrosion and loss due to working in a vacuum environment, resulting in a long service life and reducing the frequency and cost of equipment maintenance.

Traditional brazing furnace: The equipment investment cost is relatively low, but the welding quality may be affected by environmental factors, resulting in a high scrap rate and increased production costs.

5. Intelligence level

Electric heating vacuum brazing furnace: With the development of technology, modern vacuum brazing furnaces often have complete safety protection measures and intelligent management systems, which can monitor equipment operation status, process parameters, etc. in real time and perform remote control, improving production efficiency and safety.

Traditional brazing furnaces have relatively low levels of intelligence and usually require manual monitoring and operation, resulting in relatively low production efficiency and safety.
