Materials & Welding

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?

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. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- On Sat, 26 Jul 2025 at 15:34, ROHAN SONI < sonirohan94@gmail.com > wrote: Dear Team,  I am working on a material called ET45 micro (GX45NiCrSiNb45...

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...

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  On Sat, 26 Jul 2025 at 2:04 PM ROHAN SONI < sonirohan94@gmail.com > wrote: 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.  -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

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.  -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

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.

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

 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.

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.

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.

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?
