Description
The techniques of vacuum brazing and vacuum soldering are presented. Initially, we demonstrate how vacuum assists in the reduction of specific metal oxides, which significantly enhances the wetting of the braze material. Examples of metal-to-metal brazing and soldering are then shown. The scenario of the assembly and brazing of large accelerating cavities, specifically Radio Frequency Quadrupoles (RFQ), is exposed in greater detail to present a comprehensive procedure tailored for high-precision, larger-scale assemblies. Lastly, the process of brazing ceramics using both techniques, with metallisation and with active brazing alloy, are explained.
