Brazing is a process which consists in joining two metallic items by melting a filler metal used as a joint, such as copper, cobalt or nickel. This metal joining process takes place at high temperature, in a controlled atmosphere or under vacuum, to insure homogeneity and quality of the process. Indeed, a rapid heating up with no overshoot and an atmosphere without oxygen prevent oxydation and ensure the quality of vacuum brazing processes.

There are several advantages when vacuum brazing. It is a profitable process that easily fits in metallic parts’ production. Also, the dilution of the metal to be joined is low since the filler metal should have a lower melting point than the adjoining metal.

Within ECM Technlogies, we apply our vacuum furnaces’ technology to brazing. Temperature homogeneity and the absence of oxygen ensure the full mechanical integrity of treated parts and of oxidation sensitive assembly at high temperature. Our solutions are nimble enough to adapt to different kinds of atmospheres and required thermal profiles (heating speed, maintaining time, cooling speed, control of overshoots).
Moreover, pieces can be treated by batch, which implies a significant increase of productivity and of profitability.

Finally, we offer solutions with transfer systems tnat limit moves during the solidification phase. This ensures a treatment of premium quality since it reduces distortions and internal stresses. Moreover, the ECM Technologies’ range fulfills the needs of laboratories as well as of  large industrial lines requiring high capacities. This allows ECM Technologies to adapt to various production flows.
