Which organization sets the standards for structural steel welding?

The organization that sets the standards for structural steel welding, specifically through the AWS D1.1 code, is indeed the American Welding Society (AWS). The AWS D1.1 Structural Welding Code – Steel provides comprehensive guidelines that cover the requirements for welding in steel constructions, offering direction on welding procedures, welder qualifications, and acceptance criteria to ensure safety and integrity in structural steelwork.

The AWS D1.1 code is essential for anyone involved in structural steel welding, as it establishes industry-recognized standards that help ensure consistent quality and safety in welding practices. This code is widely respected and utilized across the industry, making it the primary authority for structural steel welding standards.

Organizations like ASTM, API, and ISO also provide standards and specifications related to materials, processes, and safety, but they do not specifically focus on structural steel welding in the same comprehensive manner that AWS D1.1 does. Thus, the AWS D1.1 is the definitive source for structural steel welding standards.
