What is the innershield process?

• A. FCAW-S
• B. SMAW
• C. GMAW
• D. GTAW

Answer: (A)

Self-shielded flux-core arc welding uses a hollow electrode that contains flux. When you weld, the flux provides the shielding atmosphere and produces slag, so no external shielding gas is needed. This is exactly what the innershield designation refers to—the self-shielded version of flux-core welding. It’s especially handy for outdoors or windy conditions where bringing and regulating shielding gas would be difficult. The other methods rely on shielding gas or a coated electrode for protection: gas-metal arc welding and gas-t tungsten arc welding require a shielding gas, while shielded metal arc welding uses a coated stick electrode for arc protection. So the innershield option corresponds to FCAW-S.
