A-Number vs. Nozzle Orientation Marker Pro Utilizzo e statistiche
Background
The A-Number is essential variable in most of the welding process in ASME Section IX. 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.
Competitive Edge
There is no app available in the market to determine weld metal A-Number. User mostly compare weld metal composition against ranges given in ASME Section IX. This handy tool makes life easy by comparing the chemical composition to that of the ranges for given A-Number and provide accurate result.
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.
