Which statement best describes the 4G plate position?

• A. It is the overhead groove
• B. It is the flat groove
• C. It is the horizontal groove
• D. It is the vertical groove

Answer: (A)

In welding, plate positions are named by how gravity and accessibility affect the weld. The fourth position is overhead, meaning you weld from underneath the joint with the plate positioned above you. This setup is specifically described as an overhead groove, which is why that description matches the 4G position best. The flat, horizontal, and vertical descriptions correspond to the other positions (flat, horizontal, and vertical), not the overhead case. In overhead welding, you’re managing gravity pulling molten metal away from the joint and slag running downward, making technique adjustments important.
