Flux for Welding Electrodes

It is superfluous to emphasize the importance of the materials constituting a welding electrode. If the base metal must surely be the one that is suitable for the material on the surface over which it will deposit, the importance of the coating is also crucial, both to achieve adequate ionization of the air favors the arc stability and to create an appropriate layer of molten slag which protects the weld properly.
