Which welding position is designated by 1G?

Which welding position is designated by 1G?

• A. Flat position
• B. Horizontal
• C. Vertical
• D. Overhead

Answer: (B)

The main idea being tested is how welding position codes convey the orientation of the workpiece for a groove weld. The 1G designation indicates the groove weld is being performed on a horizontal-position plate, so the correct description is the horizontal position. This code tells you how gravity will interact with the molten weld pool and guides the technique you use (travel speed, weave, and torch/wire handling) to control sagging and distortions. The other positions describe the same type of weld on different plate orientations—flat, vertical, or overhead—each with its own technique requirements, which is why they aren’t the right match for this code.
