I am using COSMOSWorks Pro to evaluate a pressure vessel with combined temperature and mechanical loads. The software has a feature to get a linearized stress output across a section of interest and produces these nice graphics with the stresses plotted across the section distance. There are six...
I just got an e-mail from Steven Rossi.
This has already been opened as BC07-1709, and will be revised in the 2008 Addenda.
The correct reference should be paragraph 5.2.2.

Thanks for the background jte.
I submitted a request for clarification to the S/VIII secretary. I have been working with Div 1 for a couple of years and am trying to learn my way around Div 2, so I had no idea that Annex 5.A had its origins in another Code.
Is there more detail & discussion in...
Thanks TGS4,
I will do this. I have written the Secretary before asking for an interpretation using the format that is given in all of the Code Sections. This inquiry for clarification does not fit the format for interpretations or code cases.
In your opinion, may I write to the secretary...
I'm looking at the 2007 Edition. Annex 3.B is titled "Requirements for Material Procurement (Currently Not Used).
Annex 3.A is tilted "Allowable Design Stresses (Normative)". This section lists allowable materials and referrs to Section II-D, tables 5A and 5B for allowable stresses.
Could the...
In 5.A.1 Scope, the paragraph referrs to stress limits in Appendix B1. Appendix B1 is refferenced again in 5.A.3 c).
Where is this Appendix B1? Is it in Section II-D?
Thanks in advance,
Chuck
Another point about ERNiCrMo-3 to consider is how it will be used in the joint. This filler metal contains ~9% Mo, which is a powerful ferrite former. If you are GTA welding pipe with an open-root joint, the root will have a lot of Mo because the filler metal is diluted the least in this pass...
Thanks Maui for the great post and reccomendation.
The Nikon representation is not as good in my area as is the Olympus and Ziess, so the Nikon instrument is dropped from the candidates in my case as well.
So I will be evaluating the Olympus microscope next week and the Zeiss the week after...
You need to specify what grade of alloy you want to discuss.
Foundries will reduce the amount of Ni, Cr, and other expensive alloy to the bare minimum as a practice to optimise profit, provided they can still make the required chemical and mechanical properties. The specification for the alloy...
If this is a chronic problem, you can change the purchasing agreement with the foundry to supply the casting to you in the rough-machined condition to solve the problem. The amount of machine stock to your final machined surface will depend on the size of the casting.
The key is to have the...
Thanks again for your continued discussion and insight into this subject. I have contacted the sales guys about demonstrations and they are happy to set this up.
Are you guys aware of any trade shows coming up where I could get a look at all the instruments at one place and time?
Most of my...
Are there mill test reports or property data from texts or codes for the materials you are looking working with? I'm not familiar with the alloys you listed.
The tensile test data should have value for elongation, listed as a percentage. Ductile materials have elongation values around 20 to...
Thanks for all of your input and ideas. I thought if I asked for your opinions I would get some! I really appreciate it.
I especially appreciated dbooker630's remarks about the Pax-Cam. The Olympus sales rep wants to package his scope with the Pax-Cam camera and Pax-it software. He says that...
Hi,
I am a mechanical engineer / welding guy with just enough metallurgy experience from my last job to be called the "expert" in my present job.
I need to buy a reflected-light microscope for some metallography work. I will be using BF,DF, DIC and Pol observation methods. I have quotes from...
