Question: A structural steel fabrication shop is bidding on a bridge component project that requires welding to CSA W59. Which of the following is a mandatory certification requirement for the welding company itself under CSA W59?
Answer options: ✅ Certification to CSA W47.1, 'Certification of Companies for Fusion Welding of Steel'
- Certification to ISO 9001, 'Quality Management Systems'
- Certification to CSA N285.0, 'General Requirements for Pressure-Retaining Components and Supports in CANDU Nuclear Power Plants'
- Certification to AWS D1.1, 'Structural Welding Code – Steel'
Correct answer: Certification to CSA W47.1, 'Certification of Companies for Fusion Welding of Steel'
Explanation: CSA W59, 'Welded Steel Construction (M-series)', explicitly references and requires companies performing welding to be certified to CSA W47.1 for fusion welding of steel. Other certifications like ISO 9001 or specific nuclear standards are not primary requirements for W59 compliance, and AWS D1.1 is an American standard, not a Canadian one for this application.
