Can radiography be used to evaluate GMAW welder or welding operator qualification test plate assemblies?

• A. Yes
• B. No
• C. Only if the Test Plate Is Steel
• D. Only With a Hold Point

Answer: (A)

Radiography is a nondestructive examination method that can be used to evaluate the welds on GMAW welder or welding operator qualification test plate assemblies. It allows you to see inside the weld and detect hidden flaws such as porosity, cracks, lack of fusion, or slag inclusions along the full length of the joint, which surface tests might miss. Using radiography helps ensure the welder’s test welds meet the required quality without destroying the test piece, provided the technique, film or digital image, sensitivity, and acceptance criteria are defined in the qualification method and are appropriate for the plate material and thickness. The evaluation can be performed as part of the qualification process without requiring a hold point, and it doesn’t limit itself to steel only if the material and technique are suitable.
