What will oxidation be prevented by during the brazing process?

During the brazing process, oxidation is prevented by covering the joints and parts with flux. Flux is a chemical compound that facilitates the joining of metals by promoting wetting and preventing the formation of oxides around the joint. When metals are heated, they tend to oxidize, which can create a barrier that prevents proper bonding. By applying flux, it forms a protective layer that inhibits oxidation, allowing for better flow of the filler metal and a stronger, more reliable joint.

In this context, while other factors like heating speeds or the amount of filler metal used can impact the quality of the brazed joint, they do not specifically address oxidation directly. Therefore, using flux plays a crucial role in ensuring a clean surface is maintained, which is essential for achieving a successful brazing process.
