Which of the following is a true statement about shielding gas in GTAW?

Explanation:
Shielding gas in GTAW provides a protective envelope around the arc and weld pool to keep air, especially oxygen and moisture, away from the hot tungsten electrode and molten metal. This prevents oxidation and contamination of the weld, helping maintain a clean, sound weld bead and a properly fused joint. It’s not about removing fumes, reducing UV light, or cooling the base metal—the gas’s primary role is to shield the weld from atmospheric gases so the weld quality isn’t compromised.
