Specialized in VACUUM BRAZING

Vacuum brazing process is a unique method to join parts. During the brazing process the braze material melts and flows into a joint by capillary force, creating a gas-tight seal. Brazing temperatures are between 900 – 1200 degrees under vacuum of one millionth of atmospheric pressure (<0,001 mbar). Vacuum brazing does not require any flux or other additives and therefore no cleaning or passivating processes are required.

BENEFITS

- Outstanding corrosion resistance- No need for post-process cleaning treatment- The most effective process to join comlex structures- Uniform heat treatment without thermal stress

Vacuum treatment ensures that brazed units do not react with the ambient gases, ensuring high quality seam. Brazing operation can be carried out not only in vacuum but also in shield gas atmosphere. All Loval vacuum furnaces can use nitrogen and the latest one also argon and hydrogen as shield gas. The latest brazing method at Loval is diffusion brazing which allows joining of components without filler metals.
