Which organization develops standards for filler metals used in welding?

The American Welding Society (AWS) plays a crucial role in setting the standards for filler metals used in welding. AWS develops and publishes specifications that cover the classification, testing, and quality assurance of filler metals. These standards ensure that the materials meet the necessary performance requirements for various welding processes and applications.

AWS documents are widely referenced in the industry and are essential for ensuring that welders and fabricators have access to reliable and consistent filler materials. The organization's comprehensive approach facilitates the creation of reliable welding procedures and enhances safety and quality in welding operations.

While organizations like the National Institute of Standards and Technology (NIST) and the International Organization for Standardization (ISO) also address standards related to materials and processes, the specific focus on filler metals, such as classification and specification, is predominantly handled by the American Welding Society. This makes AWS the primary authority on this subject in the welding community.
