What items must be included in a Quality Control Plan according to AWS D1.1?

A Quality Control Plan as outlined in AWS D1.1 must encompass comprehensive elements that ensure effective oversight during welding operations. It includes inspection processes that outline how and when inspections will be conducted to verify that welding work meets specified standards. This is critical for maintaining the integrity and quality of the welds.

Additionally, the plan must detail personnel qualifications, which are essential for ensuring that those performing welding and inspections have the required skills and certifications. Qualified personnel are vital for adhering to safety and quality requirements set forth by the code.

Procedures for handling non-conformance are also crucial. These procedures establish a clear protocol for addressing any deviations from the standards, ensuring corrective actions can be taken promptly to mitigate risks or defects in the welding process.

The other choices do not cover the full scope required for a Quality Control Plan per AWS D1.1. For instance, solely listing inspection processes and material lists lacks essential components such as personnel qualifications and non-conformance procedures, which are fundamental for effective quality control. Similarly, focusing only on training schedules and maintenance records does not address the critical inspection protocols necessary for maintaining quality in welding operations. Thus, the comprehensive view presented by the first choice is aligned with the requirements of the AWS D1.1 code.
