Big West Machine and Welding Ltd. provides CWB certified welding in Alberta. Our welders, processes, and work satisfy strict CSA standards and are certified. We have ongoing CWB audits and welder qualification tests.

Your welds will be safe, dependable, and consistent with the CWB code, and you will have full documentation and traceability.

Why CWB Certification Matters

Welders and supervisors who meet CWB standards.
Written welding procedures (WPS) and procedure qualification records (PQR)
Ongoing audits by CWB to ensure our work is up to standards
Material traceability, weld maps, inspection reports, and data retention
Reduced risk, consistent results, and better lifecycle performance

Every weld is performed according to Canadian codes and follows regulated, repeatable steps.
