Thank you all for the suggestions and feedback. I can't be sure I will utilize it in this instance, but it definitely is good knowledge for the future. More is always welcome, of course. Due to the holiday season we are stuck regarding what to do for now.
If the difference was in the realm of noise, I would just take that as a non-issue, since anyway the tolerance on the diameter is ~20%.
Still, we are nonetheless interested in the end product, which is a very small flow of gas through the hole. We can measure it, and we can do it before and...
The way to achieve even a 20% tolerance on such a small hole, is to make lots and throw away the (most) which don't comply. So indeed, we though about doing the machining after the welding, but then the cost would skyrocket by an order of magnitude. These are ultra-clean (thus ultra-expensive)...
Orbital-welded, which is basically a fully automated gas tungsten arc welding process (GTAW).
Here's an example of what such a weld would look like on similar parts:
I am looking into orbital-welding the shown stainless-steel part to an ss tube and some couplings. However, some colleagues have expressed concerns that the welding process will warp the tiny, tiny 2 micrometer restriction hole at the end, possibly closing it or making it too large. I have a...
Thank you all for the suggestions and discussion. I didn't respond in a while as I was rolling everything over in my head.
I didn't inted to withhold information in order to "waste people's time guessing". I just wanted reduce the problem in its most basic and simplest form, so as to avoid...
I think that note "bolts to be replaced w/sliding pins" on the diagram clouded what I was trying to say. The intention IS to only replace maybe 2-4 of the bolts with pins, and even then only during mounting/removal...but certainly not all of them :)
First of all, thank you everyone for the help. I wasn’t expecting nearly this much this fast!
Let me explain a little better what's going on here. The "Blue thing" on the right is a ~100kg vacuum pump which is normally bolted onto the light blue flange on the left using something like 40 bolts...
the moment would get reacted as a couple in the two beams (th eupper one in tension, the lower compression);
That's the thing I was first thinking...but then how can the load put the bottom in compression and the top in tension, if it's free to slide on the pins?
Hello,
I have a situation with a cantilevered beam with a point vertical load AND a moment load. A combination of the two following scenarios:
I did the calculations, and basically the beam will fail. So I’m wondering what will happen if I put this load on 2 beams spaced vertically apart...
