State to types of electrodes used in welding?

1. Consumable electrodes: These electrodes are consumed during the welding process and are typically made of materials such as mild steel, stainless steel, or aluminum. They provide the filler material needed to create a strong weld joint.

2. Non-consumable electrodes: These electrodes do not melt during the welding process and are typically made of materials such as tungsten. They are used in processes such as TIG (tungsten inert gas) welding, where the heat generated by the electric arc is used to melt the base metals and create a weld joint.
