If a Welder's qualification test plate assembly is assessed by radiography, what portion of the weld is evaluated?

• A. The Entire Weld Including Root, Fill, and Cap
• B. Only the Root Pass
• C. Only the Cap Pass
• D. Only Porosity

Answer: (A)

Radiographic inspection looks inside the weld to catch internal flaws, not just surface deficiencies. When a welder’s qualification plate is evaluated by radiography, the goal is to examine the entire weld cross-section—from the root through the fill to the cap. This full-coverage check ensures any potential defects, such as lack of fusion at the root, incomplete penetration, porosity, slag inclusions, or cracks, would be detected anywhere along the weld. If you only inspected just the root or just the cap, problems in the other portions could be missed, and focusing on porosity alone misses other defect types. So the radiograph assesses the whole weld to verify overall soundness.
