Nautical Term: Flux

Definition of Flux

Flux is a substance, such as borax, used in welding to facilitate the melting process of the metal. Flux plays a crucial role in stabilizing the electric arc, ensuring a steady flow of filler metal into the weld, and protecting the weld from oxidation. For instance, in the process of TIG (Tungsten Inert Gas) welding, the use of flux ensures a more consistent and high-quality weld.
