@brimstoner, @SnTMan, @MintJulep,
@r6155 by the user do you mean the owner or the main contractor ? can you clarify what you mean ?
Thanks a lot.
Hello professionals,
Recently I am facing a new situation where a welded joints between two pressure vessels manufactured as per two different standards. We need to weld a nozzle from the first pressure vessel (Vessel A) to the facing nozzle in the second pressure vessel (Vessel B)
- According...
@gtaw,
- Perfect as usual :D but what would you actually do if you were me in that situation ? follow the existing WPS ? or make a chemical analysis, or make a new WPS for that electrode ?
- Solutions and actions need to be taken and is there any references for those actions?
@weldstan
- I...
@DekDee,
- A great approach that I will use of course, Thx for your time and thx for you advice.
@david339933,
- on our WPS, Its clearly stated that preheat temperature shall be maintained. (Preheat Maintenance | Yes)
- The time of application of PWHT or this delay between Welding and PWHT...
@Dhurjati Sen, A great approach that should be respected and considered | Thx for you interest.
@mfgenggear , General speaking you are 100 % correct but what i meant with my questions is how actually i would do so i.e. how to check the current to record it what is the best method in those...
Dear Members,
Hope you are all well!
I am facing a situation where we already have done welding of two joints (φ24" | thickness of 18mm | Material. A387 Gr11 Cl2) which is a in process piping job according to B31.3.
What happened that one of my colleges already did all checks during welding...
Dear Members,
Hope you are all well !
I am facing difficulty in finding the A-Number for a TIG rod Identified AS ( AWS A5.14| ERNiCr-3 ).I have to use it for welding of SS to C/S in a High Temperature Application. Checking our WPSs, I need to know the A-Number for that electrode to proceed...
Dear Members,
Hope you are all well!
Recently I am facing problems with monitoring those parameters ( Volt, Current, Travel Speed, Shielding Gas Quality and Flow rates)on-site and i am seeking advice on what is the best approaches to do so at the following situations;
***To make it clear and...
@Kingero. Thanks for your reply i will check carefully all manufacturers catalogues or datasheets hoping to find such data if available
@weldstan, Even it would be hard to do that now, but I will try this option as soon as the work allows to, thanks mate for you valuable advice.

Hi all,
Hope you are all well !
I need help with calculating the excepted weld path size for a specific electrode size for SMAW GTAW and FCAW.
- For example what is the expected weld pass size for SMAW welding with an electrode that has a Φ 4mm
- The same also for expected weld pass size for...
Hello All,
Hope you are all well!
I have a question related to ASME IX Welding Procedure Qualification
- To solve a situation for electrode welding of some thick C/S materials, I already found an Old SMAW WPS - of my company - which can be used and it requires preheating before welding of...
- @ironic metallurgist, Since I don't know how to back off such productive discussion with you, please let me remind you that you with your free will entered this thread and commented on it and no one forced you to do that so as you said you don't do charity work so it would be a smart and logic...
@ironic metallurgist. :D Recently, Interweb - in your case - have no replies for a real world issue and seems to be busy making some sort of phrases and expressions :D Thx for your useful and effective comment :D and from your point of view, Next time i won't ask.
@Dhurjati Sen , Thx too much...
- For your question, above the plate its the Main Lower Header fot that boiler and its not a plate it's a "Header"
- Your speech from the engineering point of view is perfect but from the codes point of view i think we need to go deeper so let me discuss three solutions or 3 thoughts that I...
Dear Gents,
- Welding of this support needed to this reinforcing pad in a Power Boiler that is constructed according to ASME Sec I, In this situation with the all parameters indicated in the picture (Weld Size, Materials and Thickness ),
My question is about Preheating or PWHT Requirements...
Dear Gents,
Is it allowed to tack weld with GTAW and do the final welding with SMAW process for filet welds according to ASME Codes ?
Thanks in advance
Dear Gents,
I have a problem understanding Table QW-451.4 in ASME IX so i will go with direct questions hoping the answers will solve my confusion.
- According to table QW-451.4 If i have a WPS with a qualified range for groove welds from 3mm to 25 mm can i use this WPS to weld a fillet joint...
