[MW:35738] ASME IX WPS Qualification Query: GTAW + FCAW with Multiple PQRs

Dear Welding Experts,

I'm currently preparing a Welding Procedure Specification (WPS) and have encountered a request to qualify a GTAW + FCAW(IMPACT+PWHT) process combination by referencing two different Procedure Qualification Records (PQRs). The first PQR on hand covers GTAW + SMAW + SAW(Impact+PWHT) while the second covers GMAW + FCAW.

My concern is that combining these PQRs in this manner for a GTAW + FCAW WPS might not align with the requirements of ASME Boiler and Pressure Vessel Code, Section IX. 

I would appreciate clarification: Is it permissible under ASME Section IX to qualify a GTAW + FCAW WPS using these two separate PQRs? If not, which specific clause(s) in ASME Section IX address this limitation?

Regards 

Saurabh Jain

Re: [MW:35739] Bend Test and Tensile Test failed for ET45 Micro Welded Coupon

For welding ET 45 Micro (GX45NiCrSiNb35-45), the typical procedure involves using a nickel-based filler metal like UTPA 3545Nb 

(as Mr. Mahesh recommended) or its equivalent CEWELD 3545 Nb (both are classified under EN ISO 14343-A standards) and 

designed for welding Ni-Cr-Nb-Si based high-temperature cast alloys.  

Generally, no preheat or PWHT is required for ET 45 Micro, but it should be welded with controlled heat input and limited interpass 

temperature (monitored properly) around max 150°C. Preheat may be applied if welding thick sections or to reduce residual stress, 

but it must be confirmed with field testing. 

C Sridhar.

Dear Team, 

I am working on a material called ET45 micro (GX45NiCrSiNb45-35 Material) 

Elongation is 3 to 5℅

Tensile stength -450 Mpa

Consumable- ERNICRMO-3 

Due to such lower Elongation material shows brittle fracture and immediately failed from HAZ. 

During tensile testing it is failed from Where it holds from base metal. 

Kindly provide the solution for this that how can i comply the PQR testing.

Re: [MW:35740] ASME IX WPS Qualification Query: GTAW + FCAW with Multiple PQRs

Your first PQR covers GTAW + SMAW + SAW (with Impact + PWHT), your second PQR covers GMAW + FCAW with no indication of impact or 

PWHT. None of the PQRs individually or jointly cover the specific combination of GTAW + FCAW with impact + PWHT.

You cannot take GTAW (from a PQR qualified with SMAW/SAW) and FCAW (from a PQR qualified with GMAW), unless both cover impact/PWHT 

and are qualified for the intended sequence as in production.

ASME Section IX does not permit combining processes from unrelated PQRs to make a new process combination (e.g., GTAW from one PQR and 

FCAW from another, unless the conditions of QW-200.4 or QW-200.4(b) are strictly met—typically for root/fill passes.

QW-200.4 enables the use of multiple PQRs for one WPS but strictly constrains the qualified ranges and mandates that all code requirements be 

satisfied with the intended production.

You need to qualify a new PQR with GTAW + FCAW (Impact + PWHT) as performed for production.

The code does not use language that "explicitly prohibits" such combinations. Instead, it imposes conditions; the resulting WPS must not exceed the 

qualified ranges of thickness, essential variables, base materials, and other requirements demonstrated in the PQRs.

Re: [MW:35737] Bend Test and Tensile Test failed for ET45 Micro Welded Coupon

Hi

As its %elongation is very low 

Better try buttering on jt surrace with ductile consumable like pure Ni i. E Ni1

And later weld jt with compatable UTS consumable 

While bend test use 3mm thk with 6t or above former with slow loading

Re: [MW:35735] Bend Test and Tensile Test failed for ET45 Micro Welded Coupon

Hi ,

 We have worked on same material but fillers seems incorrect ,may be you try with UTPA 3545nb.

And bent test you can't proceed similar as normal material as it's having low ductility . 

Best regards

[MW:35725] Dismillar material Welding

Dear experts, 

In my Hydro Electric Project  materials using A517Gr.F and A537CL-II. 

For A517Gr.F using E 11018M and A537CL-II using E 9018M.

Only one joint have a A517Gr.F with A537CL-II. 

Which Electrode is better for PQT. 

Your valuable guidance is highly appreciated.

Thanks with regards, 

S.Maharajan.

Re: [MW:35727] Dismillar material Welding

We require an electrode that is compatible with the higher strength and toughness of A517 Grade F, and 

It should also maintain a good weldability with A537 Class 2. 

E11018 is preferable for welding A517 Gr F, A537 Cl II, or dissimilar joints, as it matches the strength 

and toughness requirements of both materials and is designed for high-strength, low-alloy steels.  

E9018M is suitable for A537 Cl 2, and provides good toughness but may not meet the impact requirements 

for A517 Gr F at low temperatures.   

Use an appropriate preheat (150°C–200°C) as per welding codes to avoid hydrogen-induced cracking 

and interpass temperature (200°C) to control overheating.

C Sridhar.

Re: [MW:35729] Testing of heat resistant steel tubes PQR-ASME IX

If your client is referencing QW-466.19 in ASME Section IX for a bend test, it's likely a misunderstanding or 

misreference, as this clause does not appear in the 2017, 2021, or 2023 editions, nor in earlier editions.

Inform your client that QW-466.19 doesn't exist in recent ASME Section IX editions on the intended clause or test 

requirements. We can proceed with standard bend test requirements under QW-466.1 (general bend test figures) 

and QW-163 (acceptance criteria).

Re: [MW:35731] Testing of heat resistant steel tubes PQR-ASME IX

 ASME uses and approves materials from ASTM and other sources for use in pressure-related applications, 

assigning them a special ASME designation (typically starting with "SA-"). These are called ASME-listed 

materials, but not "ASME grades".

In this sense, ASME does not invent material grades. but approves and lists them for use for the code applications.   

for example,

ASTM A516 → ASME SA-516

ASTM A240 → ASME SA-240.

Hope it is clear.

Re: [MW:35733] Testing of heat resistant steel tubes PQR-ASME IX

ASTM A297 Grade HP (Cr 24-28% & Ni 33-37%) is a heat-resistant stainless steel casting alloy commonly used in high-temperature 

applications. ASTM A297 Grade HP (ASME sec II Part A and its UNS number is N08705) does not have a direct, one-to-one equivalent 

in ASME standards and modified slightly for specific applications (example: pressure vessels, piping).

For practical purposes, in ASME codes, Grade HP would be referenced under SA-297 Grade HP for applications like furnace parts, heat 

treatment equipment, or other high-temperature cast components. For a specific purpose like piping, it is referred to as ASME B16.5 -for 

flanges.

Dear all,

No. MPI can only detect defect that is 1 to 2 mm dept. Therefore the paint must have mask the defect.

Thanks.

Re: [MW:35693]

Sir, 

No, you should not perform Magnetic Particle Inspection (MPI) on a painted surface.Paint — even thin — can interfere with this process.Strip the paint from the inspection area (e.g., nozzle welds, seams, etc.)

Re: [MW:35693]

I would like to address a common misconception regarding Magnetic Particle Testing (MPT) on painted surfaces. It's important to note that performing MPT over paint requires a specific procedure demonstration. 

This involves using the same type of paint including DFT range and materials in production grade with test samples containing known defects to do the procedure demonstration.

Furthermore, depending on the asset owner's requirements, this procedure demonstration may need to be witnessed to validate the testing method.

In simple words procedure demonstration required with the same condition of the paint material which to be tested.

Please feel free to reach out if you need further clarification

Nambirajan A

[MW:35697] PT inspection after Grinding a Weld Seam?

Dear Members,

I have a question since I'm a beginner in this domain.

After a weld inspection by PAUT, a crack was detected at a certain depth. I noticed that the welders grind down the weld surface until they reach the depth indicated by PAUT, and then apply a PT test.
My concern is: isn't there a risk that the grinding process may partially close or smear the crack surface, making it harder for the PT liquid to penetrate and properly reveal the defect?

If so, this could mean that PT might give a false result, and the crack would only be detected later when PAUT is reapplied after re-welding.

Am I misunderstanding the procedure? What is the best practice in this case?

Thanks,

Re: [MW:35698]

Mpi for surface and Sub surface Free from defects.
Painted surfaces we can't create magnatic fields, also need test surfaces Free from paint,oil, grease and other foreign materials. No yes for this test ......
