This article provides information about A number in welding procedure specification based on requirement of ASME Code Section IX.
Sfa Number Chart
A number gives a similar chemical composition in a 'as weld'condition. The A number is essential variablein most of welding process in ASME Code Section IX. The Table QW-442 in ASMECode Section IX provides the list of A number. Please note the A number inWPS does not refer to the filler wire or electrodechemical composition; it refers to the deposited weld metal chemical composition.The filler metal and deposited weld metal have different chemical compositions.

Oracle jre 7 51 64 bit. The S-Number was removed from ASME Section IX in 2009. The S Number's purpose was identical to the P Number. However, these numbers were assigned to those materials included for pipework to the ASME B31 Code for Pressure Piping. These materials were also covered by the P-Number, but not the converse. However, both Mn and Si as listed in SFA-5.18 can exceed the limits of QW-442. So my question Classifying ER70S-6 as A-No. 1 - ASME (mechanical) Code Issues - Eng-Tips.

It can be obtained from procedure qualification coupon. The smallpiece of welding can be removed and chemical analysis test to be performed. Thenthe obtained chemical composition must be compared against the table QW-422 andA number to be selected.
Alternatively if your welding process is one of SMAW, GTAW,LBW and PAW processes you may use the filler metal specification or test reportof filler metal manufacturer.
Asme F Numbers
Similarly you can do same assessment for GMAW and EGWprocesses but the shielding gas should be as the same of welding procedure specification.
Again, similarly you can do the same for SAW but the fluxshould be as the same of welding procedure specification. Rammstein songs youtube. Purin to ohuro online subtitrat.
As mentioned in above, the A number like P number and F number is an essential variablein most welding processes. It means if you have a WPS and you need to use thatin other job with different A number (it means you are using different fillermetal) then you need to re-qualify your WPS because it is essential variable.The A number 1 and 2 are exceptions. You can consider it as nonessentialvariables.
The ASME Section IX Training Course is 2 days video training course and available online and the student that successfully pass the exam, receive I4I academy certificate with 16 hours training credit.
