Which option represents the 3G welding test position?

• A. Vertical Groove Weld
• B. Horizontal Weld
• C. Flat Weld
• D. Vertical Fillet Weld

Answer: (A)

This item tests how you recognize welding positions and joint types, specifically for pipe welding. The 3G designation refers to a vertical orientation with a groove weld on a butt joint. In other words, you’re welding a groove-type joint while the seam runs vertically, and gravity affects the molten metal along that vertical seam. That combination—a vertical position with a groove butt weld—is exactly what the 3G test represents, so the vertical groove weld is the correct match. For contrast, a vertical fillet weld is a different joint geometry (fillet) not a groove butt joint, so it isn’t the 3G scenario. A horizontal weld would be oriented horizontally, not vertically, and a flat weld is performed in the flat position, also not the vertical orientation required for 3G.
