Welding
Fluxes - During welding, if the metal is heated/melted in air, oxygen from the air combines with the metal to form oxides which result in poor quality, low strength welds or, in some cases, may even make welding impossible. In order to avoid this difficulty, a flux is employed during welding. A flux is a material used to prevent, dissolve or facilitate removal of oxides and other undesirable substances.
