Filler metals in a WPS are specified and classified by which organization, with ASME providing F-numbers and A-numbers?

• A. American Welding Society
• B. International Organization for Standardization
• C. American National Standards Institute
• D. Society of Automotive Engineers

Answer: (A)

The organization that standardizes and classifies filler metals used in welding procedure specifications is the American Welding Society. AWS publishes the filler metal specifications (the A5 series) that define the chemistries, properties, and suitable processes for electrodes and filler wires. When a WPS is used within ASME codes, the filler metal is identified by its AWS designation, and ASME’s code uses its own F-numbers and A-numbers to reference that filler metal family. That relationship—AWS doing the actual classification and ASME referencing it with F- and A-numbers—is why AWS is the best answer. The other organizations exist in standards work, but they do not provide the primary filler metal classifications used in WPSs.
