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
