The 4G position on plate indicates which groove?

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

Answer: (A)

Welding positions on plate are defined by how the joint is oriented relative to gravity, and groove welds follow those same orientations. The 4G position is the overhead orientation, meaning the joint is placed so you weld from above the joint. This setup is known to be the most challenging because molten metal tends to drip away from the weld and slag can trap more easily, so technique and control are crucial. So the 4G position on plate indicates an overhead groove weld. The other groove descriptions correspond to the other plate orientations: flat-groove for a flat plate, horizontal-groove for a joint on a horizontal plane, and vertical-groove for a joint on a vertical plane.
