SMAC is the acronym for which cutting process?

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

Answer: (A)

SMAC stands for Shielded Metal Arc Cutting. It uses the same coated-electrode arc concept as Shielded Metal Arc Welding, but applied to cutting instead of joining. The electrode coating creates shielding gases and slag that protect and control the molten metal as it is melted away to form a cut. This sets it apart from submerged arc welding (welding with a flux blanket) and from plasma arc cutting (which uses a plasma torch for cutting rather than a shielded arc with a coated electrode).
