The CSA W47.1 welding procedure system consists of two components:

• A. A general welding procedure specification (WPS), and a welding procedure data sheet (WPDS)
• B. A WPS and a Welding Qualification Report (WQR)
• C. A WPDS and a Welding Procedure Qualification (WPQ)
• D. A WQR and a Welding Procedure Standard (WPS)

Answer: (A)

The main idea is that the CSA W47.1 welding procedure system is built from two elements that work together to control how welding is performed: a general Welding Procedure Specification and a Welding Procedure Data Sheet. The Welding Procedure Specification is the master document that defines the rules for a welding procedure—what process to use, the materials involved, joint design, filler metal, preheat and interpass temperatures, heat input, welding positions, shielding gas, and any required post-weld heat treatment. The Welding Procedure Data Sheet accompanies that WPS and records the specific variables for a particular job or project, providing traceability and ensuring the exact conditions used on production welds are documented and verifiable.

Welding Qualification Report and Welding Procedure Qualification are about proving and documenting that the welding procedures or welders meet standards; they belong to qualification activities rather than the production procedure system itself. Similarly, a Welding Procedure Qualification or a Welding Procedure Standard isn’t part of the two-component system described for routine procedure control.

So the correct pairing is the general WPS together with the WPDS, which is why that option best fits the CSA W47.1 concept.
