SMAW stands for Shielded Metal Arc Welding. What does SMAW stand for?

• A. Shielded Metal Arc Welding
• B. Submerged Metal Arc Welding
• C. Shielded Metal Alloy Welding
• D. Structural Metal Arc Welding

Answer: (A)

The name SMAW reflects how the process works. Shielded means the protective shield is created by the flux coating on the electrode, which gives off shielding gas and slag to keep the weld pool from reacting with the atmosphere. Metal indicates the electrode itself is a metal filler. Arc shows that an electrical arc is formed between the electrode and the workpiece to melt the metal. Welding is the joining process that fuses the pieces together. Together, these words describe the common welding method known as shielded metal arc welding, often called stick welding. The other options describe different terms or processes. Submerged Arc Welding is a distinct process (SAW) that uses a flux layer that covers the arc, not the shield from a coated electrode. Shielded Metal Alloy Welding would change the meaning by replacing “Arc” with “Alloy.” Structural Metal Arc Welding isn’t a standard process name.
