About CWB Certification



The Canadian Welding Bureau certifies companies, inspection organizations, inspectors, and welding consumables through a review and qualification process to ensure that they meet the requirements for a variety of product and safety codes as well as standards such as CSA W47.1, CSA W47.2, CSA W55.3, CSA W186, CSA W178.1, CSA W178.2 and CSA W48.

In order to achieve and maintain certification, companies engaged in welding are required to have their personnel qualified for engineering, supervisory and welding and follow approved welding procedures.

Similar to the welding companies, welding inspection organizations are required to have their personnel qualified for supervisory and certified for inspection, whether it’s visual, destructive or non-destructive testing.

Individuals looking to achieve certification as visual welding inspector are required to meet standard’s experience requirements and successfully complete written and practical exams.

In Canada, a number of CSA product standards require welding fabricators to use welding consumables certified in accordance to CSA W48. CSA W48 provides requirements for the classification and certification of welding consumables by themselves or in conjunction with gas mixtures or fluxes as applicable.
