How Are Welding Electrodes Made?

Welding Electrodes are the essential components in the process of welding. We use welding to join different materials permanently. In simpler words, welding electrodes are cylindrical shaped metallic rods, coated with flux and comes in varying lengths and radius.

These rods help in making a bead of metal by using electrical currents (AC/DC) from the welding machine. The welding electrodes are classified with the class well imprinted in its body, through which we can judge the electrode coating, its penetration capability and type of current it uses.

Technically the welding electrode is made up of two parts; first is the actual metal which is formed into wires and cut into specified length and second is the flux coating where begins the chemistry role.

The metal used in the welding rod may vary from mild steel, cast iron, stainless steel, copper, brass or aluminum. The flux wrapped on these metal rods is cellulose used by plants for flexibility, powered iron, and hydrogen. Sodium and potassium are also used to make the flux and works as a binding agent. The flux coating on the metallic rod helps the electric current to flow more evenly during welding.
