Advantages and Disadvantages of Vacuum Brazing

Manfred Boretius, 16. June 2019
The modular design of components leads to simplified manufacturing processes and cost savings - but these are by far not all the advantages of vacuum brazing. Hard- and high-temperature vacuum brazing is a joining technology which can be used to...
