Standards & Codes

The art of welding and welded components are governed by codes and standards that provide guidelines, recommended practices, regulations, rules, requirements, certifications, and specifications. Every country has its own set of codes and standards that they follow. In Canada, welding standards fall under the Canadian Standards Association (CSA). Specifically, CSA Standards W47.1 and W59 govern welding, specifying qualification requirements for welders, weld quality, and welding procedures. They also outline the requirements for welding supervisory personnel, welding engineers, and certification processes for companies involved in welding steel.

To achieve and maintain certification, companies and their personnel are required to have their employees qualified for welding, welding engineering, and supervisory roles following approved welding procedures. The Canadian Welding Bureau Group (CWB) oversees the certification processes of companies, inspection organizations, inspectors, and welding consumables. In addition, the CWB carries out third-party verification required by Canadian law.

In addition to the CSA, another standards developing organization which may influence welding in Canada is the American Society of Mechanical Engineers (ASME). ASME is responsible for the development of the Boiler and Pressure Vessel Code. This covers the design, construction and inspection of boilers and pressure vessels. ASME standards and codes are found in the library's database, Techstreet.
