FCAW-GS and outer shield are the same as?

• A. dual shield
• B. single shield
• C. flux core
• D. gas shielded

Answer: (A)

FCAW-GS stands for Flux-Cored Arc Welding with Gas Shielding, and when referring to outer shield, it suggests the use of a shielding gas in conjunction with it. This method is commonly known as dual shield welding because it combines the benefits of a flux-cored electrode with an external shielding gas to protect the weld pool. In dual shield processes, the flux in the core of the wire provides some shielding as well as deoxidizers and alloying elements, while the additional gas from the outer shield offers further protection from atmospheric contamination. This dual nature of shielding helps improve the quality of the weld by reducing defects and enhancing penetration. The other options do not accurately describe FCAW-GS and outer shield. A single shield would imply the use of only one method of protection, which doesn't encompass the dual nature of FCAW-GS with an additional gas shield. While flux core refers to the type of welding process, it doesn't specifically indicate the use of gas shielding. Gas shielded might suggest a method that solely relies on gas without the use of flux in the core, which also does not convey the full nature of FCAW-GS. Thus, dual shield is the most appropriate term that encompasses both the flux core and gas shielding
