Which of the following describes a weld button?

• A. A sample of welding filler metal
• B. A type of material report
• C. A kind of nonconformance report
• D. A certification of testing methodology

Answer: (A)

A weld button is specifically a sample of the welding filler metal that has been used during the welding process. It is typically created during welding operations and serves as a small, testable piece that can be evaluated for its mechanical and chemical properties. This allows for the verification that the filler material meets the required specifications and standards set forth for the project. This is crucial in ensuring the integrity and performance of welds in piping systems because the quality of the filler metal can significantly impact the overall weld joint strength and reliability. Assessing a weld button provides essential documentation that supports the material verification program outlined in API 578, confirming that the materials used are appropriate for the intended service conditions. The other options relate to different types of documentation or processes in quality assurance but do not accurately describe what a weld button is. A type of material report refers to documentation that summarizes material specifications, while a nonconformance report documents deviations from expected standards. A certification of testing methodology pertains to the validation processes used for carrying out tests, but it does not directly relate to the weld button itself.
