What is electrode coating used for in shielded arc welding processes?

Explanation:
The electrode coating in shielded arc welding acts as flux. When the coating melts, it releases shielding gases and forms a protective slag that blankets the molten weld, keeping air out and preventing oxidation. It also provides deoxidizers and alloying elements that influence the weld metal chemistry, helping to improve cleanliness and properties of the weld. It does not primarily strengthen the weld mechanically, insulate the base metal, or act as a coolant.
