CSA W47.1: What Project Teams Should Verify. This guide explains what a project team should clarify before fabrication or field work.
Company certification and welding workmanship
CSA W47.1 concerns certification of companies carrying out fusion welding of steel. CSA W59 addresses welded steel construction. These roles are related, but company certification, individual welder qualifications, inspection and occupational safety requirements should not be treated as interchangeable.
Verify the actual company and scope
Use the official CWB directory and request current validation information for the company that will perform the work. Confirm the certification standard, applicable scope and any project-specific qualification requirements. A welder’s qualification record is not a substitute for company certification.
Agree procedures before fabrication
The project specification and qualified welding procedures establish how the work is performed. Material, thickness, joint configuration, welding position and site conditions matter. If a detail changes, obtain the required review before welding rather than adapting a structural connection informally.
Plan inspection and records
Confirm the inspection provider, acceptance criteria, hold points and reports required by the project. Visual inspection and NDT serve different purposes. Their extent and timing should come from the specification and responsible professionals, rather than a blanket promise that every connection receives the same test.
Keep site safety responsibilities clear
Hot-work authorization, fire watch, ventilation, lifting and fall protection require their own site planning and applicable safety controls. A company’s welding certification does not replace those controls or transfer all liability away from an owner or contractor.
What to send for a welding enquiry
Include the current drawings, material information, project location, access constraints, required installation scope and any specified certification or inspection requirements. This lets the fabrication team identify missing information before pricing or scheduling.
