CSA Standard Z662 requires the approval of welding procedure specifications by:

• A. The company
• B. The customer
• C. The regulator
• D. The QC department

Answer: (A)

The key idea is who must authorize the welding procedure specification before welding begins. A WPS is a formal document that defines how welds will be made, including the process, materials, joints, and welding parameters. The responsibility for approving this document lies with the organization that will perform the welding—the company (the fabricator or employer). They ensure the WPS meets project contracts, material specs, and applicable codes, and that qualified personnel are prepared to follow it. The customer may impose additional requirements, but the official authorization to use the WPS comes from the company itself, since it controls the fabrication process. Regulators set rules, but they don’t typically approve each WPS for a specific project. The QC department conducts verification and quality checks, but the formal approval authority rests with the company.
