Which AWS code corresponds to the CWB standard for consumables?

• A. AWS 5.5
• B. AWS 5.1
• C. AWS 3.1
• D. AWS 2.1

Answer: (B)

Filler-metal classifications for SMAW are defined by AWS standards, and for carbon steel consumables used in Canadian structural welding, the AWS A5.1 specification applies. This standard covers carbon steel electrodes used for shielded metal arc welding, which is exactly what the CWB consumables standard requires. The other codes refer to different families of filler metals (such as low-alloy steels) and do not match the carbon steel consumables used in typical CWB/ CSA W59 applications. So the code most aligned with the CWB consumables standard is AWS A5.1.
