1. Protects the molten weld pool from atmospheric contamination, such as oxygen and nitrogen, which can cause porosity and other defects in the weld. 2. Helps to stabilize the arc during welding, resulting in a more consistent and controlled weld bead. 3. Acts as a deoxidizer, removing impurities from the weld metal and preventing the formation of oxides. 4. Provides a shielding gas to protect the weld from oxidation and prevent the formation of slag. 5. Helps to control the cooling rate of the weld, reducing the risk of cracking and distortion. 6. Improves the wetting and flow characteristics of the weld metal, resulting in better penetration and fusion. 7. Assists in the removal of impurities and contaminants from the base metal, promoting better adhesion and bonding of the weld. 8. Helps to control the composition and microstructure of the weld metal, improving its mechanical properties and overall performance.

1. Stabilizing the Arc: Flux coating provides ionization to help maintain a stable arc. 2. Protecting the Weld Pool: It forms a gaseous shield around the weld pool to prevent oxidation and contamination from the atmosphere. 3. Slag Formation: The flux creates a slag layer on top of the weld bead, which protects the weld from atmospheric exposure and improves bead appearance. 4. Deoxidizing Agent: Flux coating contains deoxidizing agents that remove oxygen from the weld pool, reducing weld defects. 5. Alloying Elements: Flux can introduce alloying elements into the weld metal, improving its properties. 6. Arc Length Control: The viscosity of the flux coating helps control the arc length, ensuring consistent weld penetration. 7. Reducing Weld Spatter: Flux coating minimizes weld spatter by absorbing metallic droplets and creating a slag barrier. 8. Residue Removal: Some flux coatings are self-releasing, meaning they break away from the weld surface after cooling, making cleanup easier.
