GB E4313 Welding Rod

The metal core in the electrode that is covered by the flux skin is called the core. E4313 Welding Rod flux skin refers to the coating layer coated on the surface of the welding core. Flux skin in the welding process decomposition and melting to form gas and slag, play a role in mechanical protection, metallurgical treatment, improve process performance. The constituents of the flux skin are: minerals (such as marble, fluorite, etc.), ferroalloys and metal powders (such as ferromanganese, titanium, etc.), organic substances (such as wood flour, starch, etc.), chemical products (such as titanium dioxide, water glass, etc.). Welding electrode flux skin is an important factor in determining the quality of the weld.
