A certified visual inspector is examining a circumferential pipe weld with a weld gauge. The pipe has a specified wall thickness of 10 mm and the weld reinforcement is measured at 2.5 mm. The applicable code specifies a maximum allowable weld reinforcement of 2 mm for a pipe of this wall thickness. What action, if any, should the inspector recommend?

Question: A certified visual inspector is examining a circumferential pipe weld with a weld gauge. The pipe has a specified wall thickness of 10 mm and the weld reinforcement is measured at 2.5 mm. The applicable code specifies a maximum allowable weld reinforcement of 2 mm for a pipe of this wall thickness. What action, if any, should the inspector recommend?

Answer options:

• Accept the weld as it meets typical industry standards. ✅ Require the excess reinforcement to be removed by grinding.
• Order a full radiographic inspection of the entire weld.
• Conduct a dye penetrant test to check for surface porosity.

Correct answer: Require the excess reinforcement to be removed by grinding.

Explanation: Excessive weld reinforcement, beyond code limits, can lead to stress risers at the toe of the weld and is not permitted. The inspector should require the excess material to be removed by grinding to within code limits. Neither radiographic nor dye penetrant testing directly addresses excessive reinforcement, and accepting it would be a code violation.
