Without naming any names, I got a quote from someone that seems too good to be true. I am new to the plastic industry and this is a project I am working solo on. I have two questions: 1) Is there a forum with customer feedback somewhere? 2) What are the most important questions to ask the...

It seems like our document management system does not allow ids like 1234-1000 op1. So we're kind of stuck with the individual part numbers. I think as long as there is a drawing tree and make from notes then how everything goes together is obvious.

Thanks for the input. I just wanted to see if there was a way of doing it that I hadn't thought off.

The situation is this: I start with a block of material that is machined in house. It is sent out for specialized machining to vendor A. Then it comes back and is sent for specialized machining to Vendor B. Then it comes back and is finished in house. What's the best way to handle this...

Hi all, I'm trying to find resources discussing maximum fluid velocity of water in Moly or Tungsten. The actual tungsten material is 90% Tungsten infiltrated with 10% copper. So I'm considering limiting the fluid flow to copper limits for that material. Any references on either and if not, how...

edit: I see that lack of fusion is considered a planar flaw which supports using UT.

That's an interesting observation. Do you have any literature you can point me too, that backs that up? I read that UT is best suited for detecting planar flaws, while x-ray and UT are equally suitable for detecting volumetric flaws (see below). I suppose the thinking is that, you could...

Does anyone know why 100% ultrasonic inspection is mandated for e-beam welds?

I am looking at 2007 with all the addenda. I see what your talking about. That is for category 3a and 3b welds, but that is only if the cavity is designed according to Div 2 Part 4 (Design by Rule); see table 7.1. I have a Div 2 Part 5 vessel. I think the answer to my question is that the code...

I could make it with joint efficiencies less than 1. However, it looks like Div 2 doesn't allow that.

I am trying to find if in Division II there are exceptions that allow me to be exempt from NDE on e-beam welds. I have data that shows repeatable quality welds but it looks like 100% Ultrasonic Testing is always required. Assume I am only talking about Category A, Circumferential welds.

Have you checked if the interlaminate shear strain is available as a user defined result?

Yes, look at the emodif and esel APDL commands.

Any analysis you perform should represent reality. How is the sonotrode held in the actual device?

Has anyone taken one of the web based courses from the ASME? If so, what did you think of it? My understanding is that the course is completely text based; it requires that you read through the material on your own. I am not sure if there is any added value compared to reading through the code...
