Shielded metal arc welding or popularly known as SMAW Welding , is also called manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding method that uses a consumable electrode coated with a flux to put the weld. An electric current, within the type of either AC or DC from a welding power supply, is utilities to create an electrical arc between the conductor and also the metals to be joined. The work piece and also the electrode melt forming a pool of liquid metal (weld pool) that cools to create a joint. Since weld is set, the flux coating of the conductor disintegrates, giving off vapors that function a shielding gas and providing a layer of slag, each of that shields the weld space from atmospheric contamination. Because of the flexibility of the process and also the simplicity of its equipment and operation, shielded metal arc welding is one in all the world's 1st and preferred welding processes. SMAW...
