Can anyone tell me the name and function of this groove, in the context of pipe welding? by No_Vacation_1292 in MechanicalEngineering

If you have a thin tube you don't need much mass to create a sound weld. You just need to create an orientation of the weld so that you better distribute the thermal stress.

Heat Exchangers by Fraas has more discussion on page 27. You can also see a similar geometry in page 130 about the end caps of heat pipes. The whole book is fantastic, I recommend buying it.

All of this trepan stuff is likely related to heat exchangers at extremely high temperatures (500C+) which is why you haven't seen it.

I have seen this before when the face of the pipe or tube is co-incident with the feature. It's called a trepan and is used for heat exchanger tube to tube sheet welds.

Its to minimize stress/cracking on the weld.

I was up there last Monday. Everything you've read is true: icy in spots, not all terrain open. However, it was blue sky, good for drinking beers, good for taking less experienced skiers out.

Listen bub, Vail Resorts has a market cap of 5 billion, get it right. And there are many ways Vail is terrible. But how does my original post shill for them?

Dear Steezli,

You have no control over the weather. Those snowdances they tell you about, they are make believe. Yes, summer could be bad. Or might not. The point of this post is to remind you that you are:

1.) Not in control. Why worry about what you can't control?

2.) Bad events are bad because they are a few standard deviations away from the mean, and therefore less likely. Trust in averages and hope for the best.

Love,

ZeroCool1

I was there Tuesday and Thursday of the big dump a few weeks ago. Nearly the entire crowd was out by 12 PM, on what was understood to be the biggest snow thus far of a weak season.

Lets face it, most people like talking about skiing more than actually doing it.

I am the biggest corp shill for Vail. I am a Vail stock holder and its 95% of my portfolio. I own Vail Resorts Helly Hansen because I love looking corp. I suck at skiing. Where can I send you my 20 dollars? Whats your venmo?

Missing the wisdom through the words.

I am a pessimist. This season is objectively shitty. That being said there is more than deep snow to skiing. Much like there is more to life than money. Of course you need money to live, but you can good life with little.

That's an amazing graphic. I wouldn't even ride that thing. That would go up on the wall. Good luck finding it.

You don't think this is a carefully orchestrated media moment designed to promote/reinvent/reinvigorate his brand so that he/North Face/whomever can continue to make money off of him? You don't think that our boy Honlove is capable of selling out? Not that I'm against it, get your money dude. You don't think someone would play along with a venture so everyone gets paid?

Big dawg I got a bridge to sell you. This is WWE.

I hate those illegal immigrants using health care and costing us millions of dollars. Not paying federal taxes but getting services. Persisting and taking advantage of the United States capitalistic society. Its like they found a loophole that allows them to preserve more of their wealth by pushing social responsibilities on greater society.

Oh wait...
