Under CSA Standard W47.1, who bears ultimate responsibility for the quality of the welded product produced by a certified company?

• A. The individual welder
• B. The customer
• C. The company
• D. The administrative body

Answer: (C)

The company that holds the certification is ultimately responsible for the quality of the welded product. It’s the company that must establish and maintain the quality system, ensure welders are properly qualified, use approved welding procedures, and supervise the welding process to meet project requirements. The welding supervisor and individual welders play roles within that system, but the accountability for the product’s quality sits with the certified company. The customer may specify requirements and perform acceptance checks, and the certifying body audits compliance, but they do not carry the ultimate responsibility for the weld quality.
