The 3G welding test position corresponds to which weld orientation?

Explanation:
Welding positions are named by how the weld lies relative to gravity, and the 3G position means you are welding in the vertical orientation on a groove joint. This specifies both the direction of the weld (vertical) and the type of joint (groove, not a simple fillet). Because of that, the 3G test is evaluated as a vertical groove weld. Flat and horizontal describe other orientations, while overhead refers to a different, 4G position.
