What is the meaning of shielded metal arc welding?

Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

Keeping this in consideration, why is it called Shielded Metal Arc Welding?

Shielded metal arc welding is a process in which a coated wire is melted to fill spaces between parts. The molten coating floats to the surface of the molten metal to protect it from the atmosphere. Shielded metal arc welding is also called stick welding and it uses the simplest equipment of any arc welding process.

Similarly, what type of current is used in shielded metal arc welding? Consumable electrode processes such as shielded metal arc welding and gas metal arc welding generally use direct current, but the electrode can be charged either positively or negatively. In general, the positively charged anode will have a greater heat concentration (around 60%).

Keeping this in consideration, what is an advantage of using shielded metal arc welding?

Advantages of Shielded Metal Arc Welding (SMAW): Simple, portable and inexpensive equipment; Wide variety of metals, welding positions and electrodes are applicable; Suitable for outdoor applications.

What is SMAW Strand?

Shielded metal arc welding (SMAW) is a fusion welding process that uses a consumable, flux-coated electrode to create an arc between the electrode and the work piece. Molten metal travels from the electrode via the electrical arc and is deposited into the work piece.
