Process of welding

The primary process of welding is the creation of an electric arc between the electrode and the metal. This arc should be stable and maintained between the electrode and the metal. The arc is created when electricity is passed through the electrode. A consumable or a non consumable electrode can be used in the process of welding. The welding process melts down the metals and the two melted metals join in their molten form to form a slag. When this cools down, the metals are joined together where they were melted at and become one whole structure. This creates a strong bond between the two metals that does not yield to pressure or wear and tear. In case of a consumable electrode, the electrode might melt and form a part of the weld.  This will make the join even stronger between the two metals. There are many different types of welding used for different purposes.
