Flux is an agent used in welding to prevent the weld from interacting with atmospheric pressure. Flux act as a protective slag that prevents heat from getting to the welded metal as the heat gets to it first. The flux melts and produces gases that push the surrounding air back, thus preventing weld metal reaction with oxygen and other gases.
