Soldering Flux is an integral part of the soldering, brazing, and welding process, both small and large. Flux has its Latin roots meaning "flow". Soldering is similar to welding, but that it is for a smaller application of joining metals by heating the metals that change it from a solid to a liquid, bonding, and then cooling which turns it back from a liquid to a solid.
Soldering flux is an important component in the high-temperature metal joining process (soldering, brazing, welding) in that it is intended to prevent oxidation to the metals as well as allowing the heated liquefied metals to flow easily on the application.
