How to Make Graphite Electrodeshq-carbon
· If you are familiar with arc welding you will know that current flows from the electrode (rod) to the metal part to be welded. The electrode (made of materials such as steel or aluminum) may or may not contain flux cores. Then the friction generated by the current heats the electrode and melts it into a metal joint forming a strong weld.
