A-Number in WPS does not refer to the filler wire or electrode chemical composition, it refers to the deposited weld metal chemical composition. The filler metal and deposited weld metal have different chemical composition. Acceptable method of determining weld metal chemical composition is given in QW-404.5 of ASME Section IX.

Applicable Code / Edition & Standards
The weld metal A-Number determination is in accordance with ASME Section IX 2023 Edition.

Utility
This app determine the assigned A-Number based on chemical composition in a "as weld" condition. Weld metal A-Number is used for procedure qualification. Changes in weld metal A-Number may require procedure re-qualification.

Target Audience
This app targets inspection agencies, pressure items manufacturing organizations, quality control personnel, welders, welding operators, students who are involved in welding trades and institutions who are doing  procedure qualification testing.
