Brazing has proven to be a highly versatile joining process for permanently joining many different kinds of metals and ceramic materials together in a variety of industries as diverse as aerospace and automotive.

Brazing has a long history of use, dating back to the time of the ancient Egyptians, and truly came into its own as a high-volume production technique during the twentieth-century, not only via torch-brazing, but especially with the development of well-controlled continuous and batch-type brazing furnaces.  In the last few decades, the steady increase in vacuum furnace technology made vacuum brazing a preferred method by the end of the twentieth century for many companies doing brazing.

In my next article, I’ll talk about vacuum atmospheres in brazing. Yes, vacuum is still an “atmosphere” in the technical sense of the word, since the gas inside the vacuum chamber has actually not been completely removed from the chamber, and those remaining molecules of gas must not be able to interact in a negative way with the faying surfaces of the brazement.

The new column, written by brazing expert Dan Kay will be published monthly and will offer helpful vacuum brazing applications, tips and techniques to commercial and captive heat treaters alike. Dan Kay is an independent brazing consultant, who has consented to write articles on brazing for VAC AERO since many of our vacuum furnaces are used for brazing. However, his willingness to provide this service to VAC AERO readers does not imply his specific endorsement of our furnaces, but rather his desire to help VAC AERO furnace users to understand brazing better.
