The 3G position on plate indicates which groove?

• A. Vertical groove
• B. Flat-groove
• C. Horizontal groove
• D. Overhead groove

Answer: (A)

Position codes describe how the plate is oriented during the weld. In the 3G position, the plate is vertical and the weld is made in a vertical plane along the joint. That means the groove you’re filling runs up and down the plate, i.e., a vertical groove. The other positions correspond to different orientations: flat (plate lying horizontally), horizontal (welding along a joint on a vertical plate with the weld progressing horizontally), and overhead (welding from above). So the 3G setup indicates a vertical groove.
