SMAW stands for shielded metal arc welding, also known as stick welding is a manual process using a flux coated consumable electrode with a metal rod at the core. AC or DC forms an arc between the electrode and the base metal creates the required heat. The flux coating disintegrates and gives off vapours that serve as a shielded gas and provides a protective layer of slag. Shielded metal arc welding is inexpensive when compared to other welding methods. It is portable and works with any thickness and in any position.
