True or False: Radiography is always the preferred method for evaluating GMAW welder qualification test plates.

• A. True
• B. False
• C. Only for Aluminum
• D. Only When Bend Testing Is Not Possible

Answer: (B)

Radiography is not always the preferred method for evaluating GMAW welder qualification test plates. In many qualification setups, the primary proof of quality comes from mechanical testing that directly assesses the weld’s performance, such as a bend test, paired with visual inspection. Radiography can be used to look for internal defects, but it is not universally required and isn’t a substitute for demonstrating the weld’s mechanical integrity. It also adds cost, safety considerations, and may not detect all issues relevant to qualification in every scenario. The code and contract specify when radiography is required or advantageous, which means bend testing or other mechanical tests often suffice to qualify a welder. So saying radiography is always the preferred method isn’t correct.
