[MW:10548] RE: 10546] Wire and Flux

Dear Sir,

You can use the following combination:

Wire type T-PUT (Böhler Welding) Thermanit JE-308L = AWS SFA A 5.9 : ER 308L

Flux type T-PUT Marathon 213 or T-PUT Marathon 431, unfortunately both fluxes have only EN-ISO 14174 classification and no AWS.

These are respectively SF CS 2 63 DC for Marathon 213 (molten Calciumsilicate) and SA FB 2 64 DC for Marathon 431 (Agglomerated basic).

When you need to qualify according to ASME section IX, you can use one of these combinations because of QW-404.9 (c) Wire is classified according to ASME section II part C and flux isn’t qualified. When using one of these combination WPS need to be re-qualified when changing to another flux.

[MW:10550] regarding: poldi hardness bar

dear experts,

very good day all of you.

sir's we are checking hardness of pipe.for this purpose we are using poldi hardness tester.every one know that poldi hardness tester having one standard hardness bar and some value given in that bar.we are taking indentation on bar and test specimen ( that means in piping: parent metal,haz1,weld zone,haz2),after taking two indentations and matching in convertion table.for example: we obtained on pipe parent metal 2.0mm indentation and on bar it is 1.9mm.and these both values we checked in convertion table we obtain 222.my question is this reading is briness hardness value or we have to multiply with standard hardness bar value. pl clarify me

thanks & regards

[MW:10545] TEMA vs ASME

Dear All,

For many medium pressure refinery services, the minimum thickness for
shells of heat exchangers come out to be lesser than minimum limits
prescribed by TEMA 'R'.
My question is, "Should TEMA be used for inservice inspection and

Re: [MW:10528] Socket weld

Dear Hasin

What i did before was a pwht, due to Cr-Mo steel is hardenable & susceptible to hydrogen induced cracking. along of my wide experience, if you look for resolution for your technical queries or deviation from requirement that is stated, just go with technical query to your Client.

2011/3/29 hasin shaikh <hasin.shaikh@gmail.com>

Thank you sir

But problem is that its vent plug and it will going to install after hydrotest .for that only we want to use inconel 625, is there any special condition in code where possibility to weld socket weld without pwht as we weld in P22 material less than 12 mm Thk.

On Sun, Mar 27, 2011 at 6:00 PM, Fitria Rahman <t.chintaqa@gmail.com> wrote:

Dear Hasin

I would like to try to answer your question from the best of my knowledge.

First of all, let's discuss about background of PWHT. a crack mostly happen when hydrogen diffusing from a solidified weld meets with a hard microstructure which is under specified range or its parent metal. Hydrogen cracking normally occurs in the HAZ area where we can find an undesired microstructure. we also fully aware that the other benefit of PWHT is to avoid residual stress and distortion.

Why an inconel 625 is more advisable in use for welding - i assume weld for dissimilar metal - and why we not go with other electrode?
We should take a carefully when we welding for dissimilar metal. The consideration is to avoid formation of martensite. The using of enconel 625 is main factor which is contributing to avoid a crack, due to containing of 22% Cr will keep the weldment in austenite range and avoid it from martensite formation. You can check nickel equivalent and Cr equivalent in your case.

It can say that the using of enconel 625 will help you improve hard microstructure which may be happen in your case. One of your PWHT's purpose (reducing the hardness of the weld heat affected zone) now has been answered. But, let's go back to the background of PWHT. One of the other PWHT purpose is to avoid residual stress and distortion. This purpose can not be answered by using of enconel. Weld shrinkage can not be avoided. Residual stress and distortion still happen, eventhough an enconel is used.

That is why, if your PWHT purpose is to avoid residual stress, basically, the enconel is not really doing anything to the heat affected zone. Inconel can be used for dissimilar metal, corrosion resistance overlay and to help reduce residual stress. They may be useful to reduce residual stress, but it has a little effect.

if a PWHT is requested by the technical document or considered as a significant, please keep doing PWHT.

Once again, this is from the best of my knowledge and experience. Therefore, other comments are welcomed. If any, I am thanking to you.

Re: [MW:10523] Socket weld

Thank you sir

But problem is that its vent plug and it will going to install after hydrotest .for that only we want to use inconel 625, is there any special condition in code where possibility to weld socket weld without pwht as we weld in P22 material less than 12 mm Thk.

With Regards

Dear Hasin

I would like to try to answer your question from the best of my knowledge.

First of all, let's discuss about background of PWHT. a crack mostly happen when hydrogen diffusing from a solidified weld meets with a hard microstructure which is under specified range or its parent metal. Hydrogen cracking normally occurs in the HAZ area where we can find an undesired microstructure. we also fully aware that the other benefit of PWHT is to avoid residual stress and distortion.

Why an inconel 625 is more advisable in use for welding - i assume weld for dissimilar metal - and why we not go with other electrode?
We should take a carefully when we welding for dissimilar metal. The consideration is to avoid formation of martensite. The using of enconel 625 is main factor which is contributing to avoid a crack, due to containing of 22% Cr will keep the weldment in austenite range and avoid it from martensite formation. You can check nickel equivalent and Cr equivalent in your case.

It can say that the using of enconel 625 will help you improve hard microstructure which may be happen in your case. One of your PWHT's purpose (reducing the hardness of the weld heat affected zone) now has been answered. But, let's go back to the background of PWHT. One of the other PWHT purpose is to avoid residual stress and distortion. This purpose can not be answered by using of enconel. Weld shrinkage can not be avoided. Residual stress and distortion still happen, eventhough an enconel is used.

That is why, if your PWHT purpose is to avoid residual stress, basically, the enconel is not really doing anything to the heat affected zone. Inconel can be used for dissimilar metal, corrosion resistance overlay and to help reduce residual stress. They may be useful to reduce residual stress, but it has a little effect.

if a PWHT is requested by the technical document or considered as a significant, please keep doing PWHT.

Once again, this is from the best of my knowledge and experience. Therefore, other comments are welcomed. If any, I am thanking to you.

Dear sir

we have socket weld for plug joint after hydrotest with P5b to P5B material ,can we useTo weld the joint Inconel ER 625 to avoid PWHT?

Re: [MW:10522] orientation of Check valve

Dear Sir,

Thanks for your valuable reply... I got massage from
some friends they are said to me, "can changes the orientation only
with spring type swing check valves but the flapper type swing check
valve cannot changes the orientation". Any way thanks for your advise
once again.

[MW:10519] Re: WPS

Point no 1
as per EN ISO 15607 clause 7, a WPS is A qualification is valid
indefinitely for the ranges qualified unless otherwise specified.

Point no. 2
For that you should need to know what is the yield strength of the
filler wire, if it is relative to S355 JR, then you can weld S355 JR
to S355 JR, or if it is relative to
S275 JR, then its not qualified.
Yes you can weld S275 JR to S275 JR with this WPS.
Because both material are from the same material group and your filler
wire properties are relative to it..

Sandeep Kumar

[MW:10518] Re: SS 304 WIRE WELDING

Hi
Can you please tell wht is the length of the wire for welding.
One method is to weld by flash welding and also you can use micro TIG
welding (welding with a very Low weld parameters) with proper
fixturing.
But its better if you can provide the dimension of material to be
weld.
