SMAC stands for which cutting process?

• A. Shielded metal arc cutting
• B. Shielded metal arc welding
• C. Submerged metal arc cutting
• D. Shielded metal arc drilling

Answer: (A)

SMAC stands for Shielded Metal Arc Cutting. The name shows this is the cutting counterpart to Shielded Metal Arc Welding, using the same consumable electrode and flux shielding but applied to melt away material along a cut line rather than join pieces. The shielding flux protects the molten pool and the slag helps control the cut, enabling a clean separation of the workpieces. The other options mix up welding terminology or use nonstandard terms, so they don’t describe this cutting process.
