Which of the following is NOT a weld check performed during the welding portion of the initial B-pressure test?

• A. Check tacks (max 3/4")
• B. Check 2G root
• C. Check 5G fill/cap
• D. Check 3G position

Answer: (D)

The welding portion of the initial B-pressure test focuses on validating welds in the horizontal/flat sequence typical for pipe joints. Tack welds are checked to ensure alignment and containment of the parts before welding proceeds. The root pass in a 2G (horizontal) configuration is checked to confirm proper penetration and alignment at the weld root. The fill and cap in a 5G (horizontal fixed) configuration are checked to ensure proper bead shape, fusion, and coverage through to the final cap. These checks verify the essential weld quality in the positions used during this stage. Checking the 3G position relates to welding in a vertical orientation, which requires different setup and inspection criteria and is not part of this initial welding sequence. That vertical-position assessment is addressed in a separate stage or test, not in the welding portion of the initial B-pressure test.
