Re: [MW:25638] Base metal qualification range of unlisted material as per AWS D1.1

Dear Shaik,

Please note that S355J2 or JR Materials are unassigned materials without P nos, so you have to qualify with the actual base material in this case.

However you can approach the clients by saying that the yield strength is same and the consumables used also will be same, in that case may be they will accept.

Re: [MW:25633] Hardness for vessel after PWHT

Dear All,

Many thanks for your valuable feed backs. Also regret for the late response.

Regarding the above, there was a mis-understanding that is in fact HAZ
& base metal hardness was restricted to 225 HB while weld metal was at
236 HB. since one party raised this assuming 225 HB is applicable for
all. Anyhow, all are within limit and hence OK.

The testing was done with portable machine (MIC 10).

I have one more query, when & where Brinell & vickers applicable specifically.

Thanks in advance,
Kumar.

Re: [MW:25632] WPS - In service welding

Dear Waqas

السلام عليكم ورحمة الله

Please advise us about the following
1. We are preparing a new WPS for in-service welding.
2. Our scope is mechanical sleeve type b pipeline repair.
3. The pipeline operation condition has several flow rates.

do we need to make individual WPS for each flow rate, or one WPS could be applicable for all the flow rates?

Thanks,,,

Dear Waqas

 

Use the attached test assembly (Figure-B-2) given in appendice-B of API-1104.

Then attached the pump with known flow rate with its "fluid in" nozzle during welding to simulate real welding conditions.

Using water during PQR test will qualify all the flow rates and flow media because water produces severe thermal conditions.

Re: [MW:25631] Re: Open Root Pipe Welding / Groove Welding with FCAW Process

FCAW not recommended as it is high heat input process . The toughness of the root is affected  . The most important is to control the heat input at root as it is the most important run in the weld . That why GTAW is mostly recommended and it's a clean process . STT Lincoln or RMD miller is ideal as the current characteristic is well controlled and therefore the heat input . So to be on safer avoid FCAW for X-ray quality weld .

My queries are as follows :

1.     Is it possible to weld a root run for X quality penetration  with  FCAW Process?

2.    There is any restriction for root  run welding  with FCAW   by any Welding Codes  like ASME Sec. IX, AWS D1.1. or  ISO 15614. ?

Thanks & Regards.

Re: [MW:25630] Re: Open Root Pipe Welding / Groove Welding with FCAW Process

1. It will be difficult  to get consistent root penetration for 8.00  mm thick  200 mm dai. 

    pipe using 1.20 mm wire in FCAW manual or auto process. It may work out for a higher thickness

    and larger size.

2. For 8 mm thick. 0.80 could be ideal and that size is not available in FCAW process.

3. Using GMAW (+) FCAW is gain not practical for 8 mm thick and also not economical.

4. GMAW process with Argon + CO2 as shielding gas may help with two pass technique.

    Again, LF may at times may affect X-ray quality 

5. Alternatively you can try Pulsed Auto TIG process with Argon gas. It may meet your requirement.

Please give me some guidelines  for above welding operation . Like,  voltage, Amps, and wire speed, travel speed, stick out,  torch angle, gas flow rate for root run  & other subsequent  run.

Few Engineers say that FCAW  are  not be recommended for open root run. They advised for  root  run  weld with GMAW process & subsequent run  by FCAW process. And I found in  ESAB Welder Guide Book . Page No. 16.  they are also  not recommended  root run  by FCAW.  on Pipe  &  Plate both.

Re: [MW:25628] Hardness for vessel after PWHT

Hi!

You can control Hardness  for higher thickness weld by increasing the preheat temperature to through thk  and also some time by increasing Soaking time  of PWHT (As NACE application PWHT is mandatory)

[MW:25624] Regarding E6013 and E7018

Dear sir,

As per API 650, above 12mm E7018 has to be use. Means up to 12mm E6013 has to use.
I have only query to ask that, why e6013 not allow to use above 12mm.


Regards
Prasad

What is not prohibited by the Code is permitted. in that case you will have two different deposited thickness also
