Final answer:
The classification of welding electrodes is standardized by the American Welding Society (AWS), which sets guidelines for electrode attributes such as tensile strength and coating type.
Step-by-step explanation:
Electrodes are an essential component of the welding process and their classification involves a system created by a specific professional organization. This classification ensures that welders can easily identify the correct type of electrode for their particular applications based on attributes such as tensile strength, welding position, type of coating, and current. The correct answer to the question is d. American Welding Society. The American Welding Society (AWS) is responsible for the standardization and classification of welding electrodes and many other welding-related standards.
Electrodes are classified by the American Welding Society (AWS). The AWS is a professional organization that sets the standards for welding and related processes in the United States. They classify electrodes based on their composition, coating, and intended use.
