Function of Electrode Coating in Arc Welding
Shielding of molten metalElectrode coating produces shield gas such as carbon dioxide under heat which can shield molten metal from atmospheric oxygen nitrogen and hydrogen This shielding is necessary to ensure no gas pockets in welding and then avoids contamination of the weld joint Stabilization of arcSome element that can stabilize the arc also added in electrode coating
