Fwd: WPS TO QUALIFY THE OF THE WELDER

[Rene Alvarado]

FE DE ERRATAS

 

Can I use a WPS qualified with the SMAW process in position 6G on pipes Copper Nickel to Carbon Steel with a thickness of 0.237” and with backing ring to qualify the skill of the welder in fillet welding with the SMAW process in position 5F on pipes Copper Nickel ( O.D. 2 ½” thickness 0.280”) to Carbon Steel (O.D. 3” schedule 160 in accordance ASME IX?

 

Thanks

Hi,

As per Table QW451.4 All Groove weld test qualified for All fillet sizes on all base metal thicknesses and all diameters.

Thanks& Regards,

Thanks Karthik but I'm sorry because the wording of my question was wrong.

Our WPS-XXX was qualified in 2012 = SMAW / Manual / P·No.: 1 Group No 1 y 2 a P-No: 34 Group No. N/A with 0.237” thickness in position 6G (SA-106 Gr. B to SB-466 ALLOY 706) with backing ring (SA-36) / Filler metal E-NiCu-7 of 3/32” and 1/8” / minimum preheat temperature 400° F and interpass temperature 600° F.

Nowadays in the year 2022 we need to qualify a welder in fillet welding according to the Figure QW-462.4(c) pipe to pipe of ASME IX using the WPS-XXX described above.

Question: Can we use the WPS-XXX to qualify the welder in fillet welding according to the Figure QW-462.4(c) pipe to pipe of ASME IX?

Thank very much

Hi,

As per QG 108, Qualified WPS's are still valid and you use those WPS's for your welder qualification according to the qualidcation.

QG-108 QUALIFICATIONS MADE TO PREVIOUS

EDITIONS

Joining procedures, procedure qualifications, and performance

qualifications that were made in accordance

with Editions and Addenda of this Section as far back as

the 1962 Edition may be used in any construction for

which the current Edition has been specified.

Joining procedures, procedure qualifications, and performance

qualifications that were made in accordance

with Editions and Addenda of this Section prior to the

1962 Edition may be used in any construction for which

the current Edition has been specified provided the requirements

of the 1962 Edition or any later edition have

been met.

Procedure specifications, PQRs, and performance qualification

records meeting the above requirements do not

require amendment to include any variables required

by later Editions and Addenda, except as specified in

QW-420. Qualification of new procedure specifications

for joining processes, and performance qualifications for

persons applying them, shall be in accordance with the

current Edition of Section IX.

Thanks& Regards,

Thanks for your technical advice Karthikeyan. S.

 

Again I have made a mistake in my question.

 

1. The performance qualification test shall be welded in accordance with qualified Welding Procedure Specifications (WPS), or Standard Welding Procedure Specifications(SWPS).

 

2. We have a procedure classified ten years ago (see figure below) WPS-XXX and we used the process SMAW (manual); materials P·No.: 1 Group No 1 y 2 a P-No: 34 Group No. N/A with 0.237” thickness in position 6G (SA-106 Gr. B to SB-466 ALLOY 706) with backing ring (SA-36) and Filler metal E-NiCu-7 of 3/32” and 1/8”.

3. Today we need to qualify the skill of a welder in according to Figure QW-462.4(c) Fillet Welds in Pipe-Performance using the same materials P•No.1 Group 1 y 2 a P-No: 34 Group N/A (SA-106 Gr. B to SB-466 ALLOY 706); the process SMAW (manual) and Filler metal E-NiCu-7 of 3/32” or 1/8”.

Question. Can we use the WPS-XXX indicated in item 2 to qualify the skill of the welder?

Yes, You can use it. See below snapshot for reference.

Also see snap shot of QW-350 as there is no changes in the essential variables for welder Qualification.

Also, find below regarding the use of WPS.

Hi,

As per QG 108, Qualified WPS's are still valid and you can use those WPS's for your welder qualification As per You can use Groove weld WPS for al fillet weld .

Therefore we can qualify the skill of a welder in position 5F (fillet), SMAW process, P-1 to P-34, filler metal E-NiCu-7  USING  a Welding Groove With Backing (WPS) with the same SMAW process, same material. P-1 to P-34, same filler metal E-NiCu-7

  QW-310.2 Welding Groove With Backing. The dimensions of the welding groove on the test coupon used in making qualification tests for double‐welded groove welds or single‐welded groove welds with backing shall be the same as those for any Welding Procedure Specification (WPS) qualified by the organization, or shall be as shown in Figure QW-469.1. A single‐welded groove‐weld test coupon with backing or a double‐welded groove‐weld test coupon shall be considered welding with backing. Partial penetration groove welds and fillet welds are considered welding with backing.

1. If you have a Groove weld qualified welder within ranges then you can use the same welder for Fillet welding without Qualification.

2. If you want to Qualify new Fillet welder then

      a. To Qualify a welder you need a WPS to weld test Joints.

      b. Since Groove weld Qualifies also Fillet welds you can revise your existing WPS to include Groove & Fillet else prepare a new WPS for Fillet welding with existing PQR.

Rene,

  Since position & Weld is not  essential variable in wps, u can use groove welded WPS to qualify welder IN fillet weld.

Dear experts , 

I need valuable guidance on following,

Overlapping of circumferential weld joint over longitudinal weld joint in pressure nozzle is acceptable ?  If yes , then as per which reference standard and clause

Thanks

[james gerald]

Sometimes it is unavoidable that some Nozzle welds overlap Circum seam or Longitudinal seam, in that case the circum seam or Longitudinal weld seam shall be flush grinded and RT performed before welding and after successful RT results the Nozzle weld may be welded over flush grinded seam and perform necessary NDT after welding.

I believe your question is Nozzle weld overlapping longitudinal seam.

Thanks & Regards
