Vacuum Brazing Techniques and Advantages
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. Brazing exhibits several benefits over other metal-joining processes, especially 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 performed in a specially designed furnace in the absence of air and delivers the following benefits:
1.Flux-free braze joints with high integrity and superior strength
2.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 heat treating of the work piece is part of the metal-joining process, but all in a single furnace cycl.
Vacuum brazing is convenient for mass production, like traditional brazing. It is used in many different industries, including automotive, aerospace, medical, and much more.
