Definition of Terms Flux - is typically a chemical compound that combines with impurities and with oxygen to prevent harmful oxidation of the hot metal - after combining with impurities the flux is in the molten state called slag - the slag solidifies and must be removed from the finished weld Inert gas - such as argon or helium - displaces the air ambient to the weld and thus keeps harmful oxygen away from the hot metals
