Shielded Arc Welding (SAW) is a process that typically involves the use of a continuously fed consumable electrode and a protective gas shield. While definitions and standards can vary among organizations, here is a general overview of how DNV, AWS, ABS, and ASME might define or approach Shielded Arc Welding:
1. **DNV (Det Norske Veritas)**:
- DNV provides classifications and standards related to quality assurance and risk management in various industries, including shipbuilding and offshore structures. Their guidelines might reference the principles and quality standards for welding practices, including Shielded Arc Welding, ensuring that it meets safety and reliability criteria.
2. **AWS (American Welding Society)**:
- The AWS standard (specifically AWS A5.17 for SAW) defines Shielded Arc Welding as a welding process that utilizes a continuously fed electrode and a shielding gas to protect the weld from contamination. AWS provides detailed standards for the equipment, procedures, and qualifications associated with this welding technique.
3. **ABS (American Bureau of Shipping)**:
- ABS focuses on safety and performance standards for marine and offshore applications. They outline welding practices, including Shielded Arc Welding, in their acceptance criteria and guidelines for structural integrity in marine vessels, ensuring compliance with safety and quality regulations.
4. **ASME (American Society of Mechanical Engineers)**:
- ASME's Boiler and Pressure Vessel Code (BPVC) includes provisions for various welding processes, including Shielded Arc Welding. The relevant sections provide requirements for the materials, workmanship, examination, and testing of welded joints to ensure the safety and efficiency of pressure-retaining structures.
Each organization emphasizes compliance with safety standards, quality assurance, and proper technique in the implementation of Shielded Arc Welding across different applications. For precise definitions and standards, it is essential to refer to the specific publications or codes from each of these organizations.
