RE: [MW:13002] Supplementary essential variable - Group number As per section IX

By Materials & Welding

See ASME Interpretation IX-79-94.   It was included in an earlier post. 

 

Short answer is no.  Only a single PQR with one base material P1 G1 and the base material P1 G2 is required. 

 

All other essential and supplementary essential variables are the same for  any combination.

Dear Sir,

 

The last sentence of 403.5 states that In addition, when base metals of two different P nos. Groups nos. are qualified using a single test coupan, the the combination is also allowed.

 

But, two or more qualification records should be there to support the above sentence.

 

Please correct if I am wrong.

The key lies on the last sentences of QW 403.5
So if you have a PQR with from one side Pno1 Gr. 1 and the other side Pno1 Gr. 2
then you can support WPS with following combinations, assuming all other essential and supplementary essential variables are in validity range:

Pno1-Grno1  to Pno1-Grno1
Pno1-Grno2 to Pno2-Grno2
Pno1-Grno1 to Pno2-Grno2

Dr. Georgio,

What is the correct one? Please provide for the benefit of us who also intrigue with this matter.

Thanks a lot.

Dear concern,
 
In this case if you have PQR with P No-1 Gr No-2 to P No1 Gr 1 combination with impact testing.
 
The following combinations with same PQR For impact application. -  CAN NOT BE USED
1) P No-1 Gr No-2 to P No1 Gr 2
2) P No-1 Gr No-1 to P No1 Gr 1
3) P No-1 Gr No-2 to P No1 Gr 1
 
But, as per QW-403.5
 
If you have two W{PS/PQR for P No-1 Gr No-1 to P No1 Gr 1 and P No-1 Gr No-2 to P No1 Gr 1 or 2 combination with impact testing., then only the above combinations are allowed.
 
QW - 403.5 clearlly states that a procedure qual. shall be made for each P No. Gr No combination of base metals, even though pro. qual. tests have been made for each of the two base metals welded to itself.

Dear Vijay,
 
Please refer to QW-403.5 of ASME Sec IX.
 
It states “ When base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of these two P-Number Group Numbers to themselves as well as to each other using the variables qualified.”
 
Hope this helps.

Sadique

Dear Nandesh,

Thanks for reply

But if toughness requirement is applicable then group number will be essential variable. as per QW 252 change in group number call for qualification.
please give me any reference in the section IX.

YES.
As per SEC IX, any combination of P1, G1 materials can be welded in any combination to P2, G2, provided Impact test requirements are fulfilled.

Dear All,

please sheared your valuable experience for following situation,

I have PQR with P No-1 Gr No-2 to P No1 Gr 1 combination with impact testing. Can i use following combination with same PQR For impact application.

1) P No-1 Gr No-2 to P No1 Gr 2
2) P No-1 Gr No-1 to P No1 Gr 1
3) P No-1 Gr No-2 to P No1 Gr 1

If above combination's are possible please provide code reference of ASME section IX or ASME section VIII.

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
