Final answer:
The CSA W47.1 welding procedure system includes the Welding Procedure Specification (WPS) and the Welding Procedure Qualification Record (WPQR) as its two components, which ensure welds meet predefined standards and possess required mechanical properties.
Step-by-step explanation:
The CSA W47.1 welding procedure system consists of two main components:
- Welding Procedure Specification (WPS)
- Welding Procedure Qualification Record (WPQR)
The WPS is a formal written document describing welding procedures, which guides welders for producing welds according to predefined standards and requirements. The WPQR, on the other hand, is a document that provides evidence that the weld produced by a specific procedure can meet prescribed standards and possesses the required mechanical properties.
