Hello,
What is everyone using for their TTS orbital joints?
We've tested Polysoude, AMI(ESAB), Liburdi, and Orbitalium.
My findings:
AMI easiest to use, but since ESAB purchase, they are unserviceable.
Polysoude, the equipment was not easy to use.
Liburdi, the equipment didn't even work...
Hello,
The production team has purchased a machine from "TIP TIG". It's a semi-auto GTAW, with hot wire, and that process I am highly interested in since we already have automatics. It also has linear actuation for the wire to "agitate the weld pool", but I've turned it off, it's garbage. Our...
Hello,
What's the current authoritative and modern references for nuclear welding and fillers, best practices etc? I do not mean applicable codes.
Thanks
Hello,
QW-200.2 (c) discusses adding additional information to PQRS as being acceptable, but follows with "All changes to a PQR require re-certification".
Has this always been the case? I'm looking through historical procedures and finding lots of data just tossed in. Added 1-5 years post PQR...
Hello,
The new 2019 code has removed the previous comment about complete penetration to within 1/64" (0.4mm). So ASME no longer wishes to comment on penetration to the root, or no longer want to enforce a tolerance? Or do they wish us to interpret c) as including complete penetration?
It seems...
Fellows,
We are going to be welding some Hastelloy G-35 to make a ASME vessel. We work with C276, C22, B2/3 occasionally, no issues. Obviously this is another class of the alloy group, and quite niche.
Any concerns different from C276? Any recommended reading? Anyone in here have experience...
Hello,
Does anyone have a textbook, papers, references, or direct knowledge on the following?
Looking to find the chemistry effects, main concern is carbon content, in GMAW welds of austentic stainless steels from various gases, Ar (no effect or reducing), Ar-CO2 (Effects at 1%, 2% ... )...
Dear All,
We've developed some new austenitic filler metals for ASME code work. No plans on getting it added to Sec II C. We have done many tests on our test heat and we are satisfied. The question is, for production of new melts, what tests should be done?
After reviewing code I see no clear...
Hello,
For reference this question is related to ASME BPVC VIII Div 1, appendix A. This is where we started.
I'm trying to justify the allowable load and the joint design on an expanded only enhanced TTS joint (type i per Table A-2). Normally we only work in welded only using A-2 with A-3...
Hello all, been reading for a while, finally have a question.
We are looking at welding some rare alloy per QW-193. Unfortunately due to the PM when the mill has our tubes ready for fabrication, we need our WPS ready. So there is no tube available for testing, but there is sheet available...
