What is the purpose of the AWS classification of filler metals?

The AWS classification of filler metals serves primarily to identify the filler material used in welding processes. This classification provides crucial information regarding the composition, properties, and intended applications of the filler metals, enabling welders to select the appropriate material for a specific welding task.

By understanding the AWS classification, technicians can ensure compatibility with base metals, predict the behavior of the filler metal during the welding process, and ultimately achieve the desired mechanical properties and performance criteria in the finished weld. This classification system simplifies the selection process and enhances communication among professionals in the welding and metallurgy fields.

Others options mentioned, while relevant to the overall context of welding, do not represent the primary purpose of the AWS classification system. The classification is more focused on identification rather than mechanical strength determination, thermal characteristics assessment, or specifying welding procedures.
