What is the AWS equivalent of the CSA inspectors standard?

• A. AWS QC2
• B. AWS D1.1
• C. AWS B5.1
• D. AWS QC1

Answer: (D)

The main idea is the framework that governs how welding quality is controlled and inspected. AWS QC1 is the standard that defines a welding quality-control program, including responsibilities, inspection procedures, acceptance criteria, and documentation. This aligns with what a CSA inspector standard would cover in Canada—how welds are inspected and how records and compliance are handled. So QC1 is the AWS standard that best matches the role of an inspector, providing the overarching quality-control structure inspectors rely on.

The other options address different purposes: one is a structural welding code that specifies how welds should be performed and evaluated in structural steel; another relates to qualifications for inspectors themselves or to a different quality-control category. These do not provide the broad quality-control framework that QC1 offers, which is why QC1 is the correct counterpart.
