Which welding position is designated by 3G?

Explanation:
3G means the vertical welding position. In the common system for groove welds, the sequence maps to orientations: flat, horizontal, vertical, and overhead. So a weld designated 3G is performed on a vertical plane, with the bead laid out along the vertical surface. This explains why vertical is the correct description—the joint sits on a vertical face, not flat, horizontal, or overhead.
