What provides the necessary information for making sound welds for ASME service?

1. Code book

2. Engineered working drawings

3. PQR

4. Welding manual

The correct answer is: Engineered working drawings

To understand the essential source for making sound welds for ASME service, it's important to consider what engineered working drawings entail. Engineered working drawings provide precise specifications that detail the design, dimensions, tolerances, and materials required for a welding project. These drawings are critical because they serve as the blueprint during fabrication, ensuring that all welding meets the exact requirements outlined for the project, thereby promoting safety and structural integrity. In the context of ASME (American Society of Mechanical Engineers) standards, well-documented drawings facilitate compliance with codes and regulations governing the welding processes and materials. They guide welders on where and how to perform the welds, what filler materials to use, and any special conditions that must be adhered to. This clarity is crucial for achieving high-quality welds that conform to the stringent requirements outlined by ASME. While other resources like code books, procedure qualification records (PQR), and welding manuals provide valuable information about standards, procedures, and techniques, the engineered working drawings serve as the definitive guide linking these elements to the specific project at hand, making them indispensable for achieving sound welds in ASME service.
