When two metal parts need to be joined, flux is applied to the surfaces before heating. This chemical agent works by cleaning away oxidation, dirt, and impurities that would otherwise prevent proper bonding. As the soldering iron heats the metal, the flux melts and spreads, allowing the solder to flow smoothly and stick firm
