Which two organizations are cited as having written specifications for wire feed filler metals?

• A. WCB and CSA
• B. CWB and AWS
• C. ASME and CWB
• D. AWS and CSA

Answer: (D)

Wire feed filler metals are governed by published specifications to ensure consistent performance and compatibility with welding processes. The organizations that write these specs are AWS and CSA. AWS (American Welding Society) develops filler metal specifications for processes like gas metal arc welding and flux-cored welding, detailing acceptable alloys, classifications, and requirements. CSA (Canadian Standards Association) provides Canadian equivalents and harmonizes with AWS so products meet North American needs. The combination of AWS and CSA is the standard pair for these specifications, while other options involve bodies that focus on certification or different codes rather than writing the filler metal standards.
