Vacuum Brazing services, Pune, India

Brazing is a metal-joining technique wherein a filler metal is used to join two or more materials by drawing it into the joint by capillary action. A filler metal is a material with a melting point lower than that of the materials to be joined. Vacuum Brazing is a process that creates high-quality joints under temperatures from about 550°C to 1150°C in a vacuum atmosphere. This also allows for the joining of different materials.

Process
Vacuum brazing is a joining process used to connect materials, typically metals, through the use of a filler metal called a braze alloy. This method involves heating the base metals and the filler metal in a vacuum environment, where the absence of air prevents oxidation and contamination, ensuring a clean and strong joint.

Advantages of Brazing over Welding

Valve components for marine, oil & gas, defence sectors etc.
Minimum dimensional distortion
Uniform microstructure due to better process control

Advantages of Brazing over Welding :

Base metals never melt, thus enabling close tolerances and joining materials neatly without going for secondary finishing
Homogenous heating of components reduces thermal distortion when compared to welding
Suitable for cost-efficient joining of complex and multi-part assemblies as brazing can easily join non-metals and dissimilar metals

Vacuum Brazing is far superior to Conventional Brazing :

Extremely clean
Flux-free braze joints with high integrity and superior strength
Improved temperature uniformity
Lower residual stresses owing to slow heating and cooling cycle, resulting in dramatically improved mechanical and thermal properties of the material
Age hardening or hardening heat treatment of the work piece is part of the metal-joining process, but all in a single furnace cycle

Filler metals used
Copper, Nickel, Silver, Aluminium

Application Industry :
