There are no domestic or international equivalents to CSA welding certification standards.

Other national systems, such as that of the American Welding Society (AWS), do not include key concepts of the CSA standards such as independent and on-going verification, witnessing of welders qualification, review and acceptance of welding procedures, witnessing of procedure qualification testing, and qualification of welding supervisors and welding engineers.

The CWB strongly cautions specifiers and owners around accepting substitutions; doing so may contravene the intent of Canadian design and product standards and place public safety at risk.

To better summarize the similarities and key differences between CSA and AWS certification programs the CWB has developed the following documents:

• Comparative Review AWS D1.1 vs CSA W47.1 & CSA W59
• CSA W47.1 vs AWS D1.1 - The Similarities and Differences
• CSA W47.2 vs AWS D1.2 - The Similarities and Differences
• Welding Personnel Qualification Testing CSA W47.1:2009 U7 vs AWS D1.1:2015
• Welding Procedure Qualification AWS D1.1 vs CSA W47.1
