Difference Between Consumable and Non-Consumable Electrode

A consumable electrode itself melts down during welding and subsequently deposits on the weld bead. A non-consumable electrode does not melt down or deposit on the weld bead. It remains intact throughout the welding. A consumable electrode acts as filler and thus it supplies necessary filler material intended to fill the root gap.
