Re: [MW:32540] change in sfa number

There are 3 points to be considered as experts mentioned as below.

1. In ASME 2021 edition SFA 5.36 has been discontinued but I suppose the recalled may be used based provided the welding consumable certificate matches with A-Number of that Qualified for PQR.

 

2. Both SFA 5.20 & SFA 5.36 falls under F-Number 6 & hence  no issue.

3. Ensure the Shielding gas as qualified for 100%Co2

Thanks & Regards

[MW:32533] Re: Is P11 to Satainless Steel(304L or 316L) welding possible?

Dear Ganesh 

The compatible filler metal shall be decided based on 

1) Service temperature 

2) Type of butt joint - Butt/ fillet 

3) PWHT required or not 

4)Service type -Elevated/corrosion  etc

Pl. state all the requirements from drawing/specs   then we experts can give suitable advice

Re: [MW:32526] PQR-Qualified in Duplex Stainless Steel UNS-31803 / WPS-UNS-32750

There are certain points to be considered.

1. Though both UNS-31803 & 32750 falls under same P-No: 10H / 1 but their UTS values are different. UNS 31803 welded using consumable ER 2209 which produces a UTS value of 90ksi whereas UNS32750 shall be welded with a consumable which has a UTS valiue of 120Ksi and hence preferred ER2594.

2. ASTM G48 tests are mandatory to ascertain its suitability to service, UNS31803 tested at temperature of 25degC whereas UNS 32750 tested at  40dgeC and hence suitable welding consumable to be selected.

3. Generally welds are considered anodic when compared with the Basemetal due to its area and corrosion are localized in welds. UNS 31803 has a PREN value of 34 whereas UNS 32760 has a PREN value of 40 due to its high alloy elements.

4. Moreover for Duplex and superduplex stainless steels are governed by various Clients specifications which will be more demanding and will not permit.

Hence WPS for UNS31803 cannot be used for UNS32750.

Hope our experts can add more points to clarify.

Thanks & Regards

[MW:32525] RE: PQR-Qualified in Duplex Stainless Steel UNS-31803 / WPS-UNS-32750

No, in most of the cases.

32750 is a SDSS(25Cr), while 31803 is a DSS(22Cr). For P10H group every grade is different, in chemistry, mechanical properties & corrosion resistance. You require separate PQR with all comprehensive testing for each individual grade.

 

What're the process requirements and intended service/s.

 

Thanks.

Re: [MW:32515] Cracking of Monel 400 TTS welds

Hi JP,
Monel being critical material from welding point of view, we have to take care of general good engineering practices like sequence of welding, proper shielding by inert gas, control of heat input, the gap (if any) between tube and tube sheets, etc. In sequence of welding try to weld the joint in multiple segments with sufficient overlaps from starting to end points. Many time the cracks develops due to minor things those are very critical to particular materials.

Dear Sir,

Pipe Size .3/4 inch sch 160 (5.56 wall thk ) 

Used WPS for welding with pwht : Temp 720 degree plus minus 20 degree 

Soaking Time 2HR 25 MIN .

as per ASME B31.3  its exempted ..as thk is less than 16mm .

but if we used wps with pwht then its mandatory to do the PWHT ?

from B31.3 Table  331.1.3 exemption of pwht

any sabic spec saying about this ??

we have socket weld (fillet weld) and Goove weld to do PWHT ..

thanks in advance 

Further to above what is the calibration range for pressure gauges in SABIC ? any standard ? or any procedure .

Toughness value will be  more than Normalizing, Welding related issues will be more in QT if proper procedure is not followed.

Dear Experts,

Below is an excerpt from ASME SA-350 and is related to product marking:

Could you please advise the basis of this requirement. In most cases, this stamping is specified for Quenching and tempered or Quenching and precipitation heat treated only unlike the Normalizing or Normalized and tempered.

Re: [MW:32507] AWS WPS & WELDER QUALIFICATION

Dear sir, 

Please note that qualification for WPS and welder are deference

For welder, he can weld F, H, V but PQR/ WPS must be qulified more

AWS Table  is very clear for WPS PQR.

For each position ,PQR is needed .

Qualify PQR positions based on  envising Production Welding Joint positions.

For Welder , range for Qualified position is given based on WPQ tested position.

Dear Experts

I need a clarification on AWS table 4.1 vs 4.10

As per table 4.1- for 3G position WPS shall be qualify for vertical position only

As per table 4.10 - for 3G position welder will qualify for Flat, Horizontal, vertical.

My doubt is if i have a WPS for 3G uphill position, can i use the same WPS for 1G&2G also ?

If not please explain.

Re: [MW:32505] AWS WPS & WELDER QUALIFICATION

Hai,

If your welder tested in 3G Position he can weld F,H & V Position.

3G PQR Will support only Vertical Welding.

If you need F&H position you need to establish New pqr with 2G position.
