What CSA standards apply to welding in Quebec?

Several CSA (Canadian Standards Association) standards govern welding in Quebec. The main ones for a QBQ welder are:

CSA W47.1 — Certification of welding companies:

• Requires welding companies to have an approved quality control program
• Classes: Division 1 (all processes, engineer required) and Division 2 (SMAW/FCAW only, limited procedures)
• A certified welding supervisor must oversee operations

CSA W59 — Welding of steel structures (carbon steel):

• The Canadian equivalent of AWS D1.1, with Canada/Quebec-specific amendments
• Defines weld acceptance criteria, WPS (Pre-qualified Welding Procedures), tolerances
• Requires the company to be certified to CSA W47.1: the certified company qualifies its own welding personnel (the standard does not certify the welder)

CSA W178 — Qualification of inspection personnel:

• Certification of welding inspectors (visual inspectors, CGSB) and testing laboratories
• Inspector levels: Level 1 (assistant), Level 2 (independent), Level 3 (expert)
