Welding Filler Metal Specifications

Welding Rods, Electrodes, and Filler Metals are organized into a two tier system of Specification + Classification.

FILLER METAL SPECIFICATION

Welding Filler Metal Specifications group filler metals into similar material types and welding processes. The specification contains many details such as the official classification designators and the testing required to certify the filler metal to that specification.

Filler Metal Specification Appearance

Within AWS the specification appears as A5.XX

Within ASME the specification appears as SFA5.XX

Filler Metal Specification by Material and Weld Process

The following table provides the details for the specifications that apply to the combination of the standard material groupings and the given weld process.
