Explanation:

Identify the core question

The question asks which organization defines "Shielded Arc Welding" (or Shielded Metal Arc Welding, SMAW) among the given options.

Analyze the options

• AWS: American Welding Society. This is the primary organization in the United States responsible for standardizing welding terms, definitions, and processes.
• ABS: American Bureau of Shipping. Focuses on marine classification and standards.
• ASME: American Society of Mechanical Engineers. Focuses on pressure vessels and boiler codes, referencing AWS definitions for welding.
• DNV: Det Norske Veritas. A marine classification society.

Determine the defining authority

Using the Arc Welding Methods knowledge base, standard terminology and definitions for welding processes in North America are officially established and maintained by the American Welding Society (AWS). Therefore, AWS is the organization that formally defines Shielded Arc Welding.

Answer:
