Vacuum Brazing
arXiv:2602.05782
Abstract
First, we describe vacuum brazing and vacuum soldering. Then, we demonstrate how vacuum assists in reducing specific metal oxides, significantly enhancing the wetting of the braze material. Examples of metal-to-metal brazing and soldering are provided. The brazing of large accelerating cavities, specifically Radio Frequency Quadrupoles (RFQ), is then explained in more detail to present a comprehensive procedure tailored for high-precision, large-scale assemblies. Finally, we discuss the process of brazing ceramics using both techniques: with metallisation and with active brazing alloy.
