VACUUM BRAZING
It is the most advanced technology in terms of reliability, cleanliness, and durability.
The process of joining materials through high-temperature brazing in vacuum furnaces, serving as a complement to welding techniques, is developing as an important and independent technology.
VACUUM BRAZING
Vacuum brazing is a flux-free process carried out by removing air, for example, in a vacuum, using brazing materials with a liquidus temperature above 900°C.
Advantages of vacuum brazing technology compared to welding in a controlled atmosphere:
no contamination of base materials and no structural inhomogeneities caused by supercooling of the weld zone,
no local overheating of the processed components (avoiding the formation of stresses and inclusions such as brittle phases with lower strength in the weld zones),
lower stresses and inclusions due to uniform heating and cooling in the vacuum furnace, the ability to join different materials and composites,
high strength of the brazed joint, no local overheating in components, no issues with corrosion.
