Gas drift is the phenomenon that results in inadequate shielding when welding in windy conditions.

Explanation:
Gas shielding protects the weld pool from air, and wind can disrupt that protective curtain. In windy conditions, drafts can push or draw shielding gas away from the arc and weld area, a phenomenon known as gas drift. When shielding gas drift occurs, coverage becomes inadequate, allowing atmospheric gases to contaminate the weld and cause porosity, oxidation, or poor bead quality. Therefore, the statement is true. To reduce gas drift, weld in a sheltered area or use a windbreak, and ensure the shielding gas setup provides stable coverage of the weld zone.
