F-No&A-No of ERNiCrMo-3

[limesh M]

Dear All,

 

I want to prepare a WPS for ,

 

material ASTM B 423 (P No-45).

 

Process - GTAW

Construction Code - ASME B31.3

Welding Code - ASME BPV SEC IX

 

What is the F - No. of ERNiCrMo-3?  43 or 45?One of the  WPS in my hand says 45 !!!

I have reviewed ASME BPV SEC IX QW 432,F-No. section and found that 43.Now I need clarification from experts,which one is correct 43 or 45?

 

What is the A - No. of ERNiCrMo-3? I have reviewed QW 422 A-Numbers section,but couldn't find.

 

Is there any condition that P- no. and F- no. shall be same?

 

Seniors, I need your help on this issue.

 

 

Regards,

 

Limesh

For ERNiCrMo-3 Fnumber is 43, please recheck WPS if they have specified some other filler such as NiFeCr-1, NiCrMo-9 falls under F45.

A Numbers are not applicable for non ferrous welds

No such condition as for P number/F Number should be same in Sec IX.

Dear All,

I’m going to make some Works inside of a dehydrator (please see attachment), the questions are:

1. If I cut the angle suports without Couch the shell, do i need an R stamp company for mantain the ASME stamp?
2. If I cut the angle suports and grinding the angle flush to shell, do i need an R company for mantain the ASME stamp?
3. For cutting the existents excentric reducers as and Weld others, do i need an R company for mantain the ASME stamp?

 

Please escuse my language, i’m not native speaker (or writer :D )

Thank in advance for your cooperation.

Hi, P.Number and F number are different and the numbers cannot be same and substituted. For ERNiCrMo-3 F-Number is 43. For A number You can check with the QW-442 along with your Filler metal certificate to compare the chemical composition.Since it is a nickel based alloy,you check with the composition of A number 10 requirments.   Pls.find below the extraction of ASME appropriate sections.    QW-404.37 A change in the composition of the deposited weld metal from one A-Number in table QW-442 to 65 any other A-Number, or to an analysis not listed in the table. Each AWS classification of A-No. 8 or A-No. 9 analysis of table QW-442, or each nonferrous alloy in table QW-432, shall require separate WPS qualification. A-Numbers QW-404.5 (Applicable only to ferrous metals.) A change in the chemical composition of the weld deposit from one A-Number to any other A-Number in table QW-442. Qualification with A-No. 1 shall qualify for A-No. 2 and vice versa. The weld metal chemical composition may be determined by any of the following: (a) For all welding processes—from the chemical analysis of the weld deposit taken from the procedure qualification test coupon. (b) For SMAW, GTAW, and PAW — from the chemical analysis of the weld deposit prepared according to the filler metal specification, or from the chemical composition as reported either in the filler metal specification or the manufacturer’s or supplier’s certificate of compliance.

Dear Raghuram sir,

 

I have reviewed my WPS and the following values observed.

 

Specification (SFA)  :  A 5.14(GTAW)

AWS classification   :  ER-NiCrMo-3(GTAW)

Trade Name            :  Thermanit625(GTAW)

 

 Filler metal product form : Solid (GTAW) 

 

Chemical composition in % for GTAW: C-0.008%, Si-0.06%, Mn-0.02%,Cr-22.32%,

Mo-8.93%, Nb-3.53%, Ni-64.10%,Fe-0.439%,P-0.001%,S-0.001%,Cu-0.039%,Ti-0.181% &Al-0.127%

 

 

Dear Karthik Sir,

 

Thank you for the correction,I had mistakenly typed QW.422 instead of QW.442

 

I have reviewed ASME QW.422 'A' No. section and couldn't find any matching chemistry with above mentioned chemical composition.

 

In this case,In the A-No column of WPS, what I have to write? N/A or Nil?

 

 

 

Regards,

F number will be 43 and A number is not applicable for non ferrous materials
