I saw this one on a site about CERN.
Its titled:
A welder works on the interconnection between two of the LHC's superconducting magnet systems, in the LHC tunnel.

Anybody have any idea on what process he's using?
Parent - - By Stephan (***) Date 08-03-2008 21:58
Robert,

I guess he is using very small GTAW Coldwire Orbital head, is welding an edge joint weld and is holding a little mirror in his hands for observing the circumferrential performed course of the seam, please see below.

By the way, I was there once and had a "private tour" guided by a PhD physicist who's working with the Large Hadron Collider project. It was tremendous!!!

Best regards,
Stephan

P.S. Really neat picture!

years ago, a company i worked for did some work on the superconduction super collider project in North Texas. Too bad it didn't come to fruition.

Rio,

who knows the day of tomorrow?

Perhaps this has still to come one day, but you have the certainty however, to have participated in this great project!

And I mean, this is not surely not common... ;-)

Best regards,
Stephan

you know where that project was at, there is actually a housing development over parts of the area now. I think it was about 1100 acres back then.
Parent - By Stephan (***) Date 08-05-2008 14:30
Rob,

thanks for the reply!

I see, then it's most probably over with this project. :-(

However, best regards,
Stephan

They still have all the huge buildings at the SSC site. You can check it out as there's no one out there to watch over it. Been a few times; most all the equipment is gone but still neat to see. Pretty neat thing to see for anyone who's interested. Right near Waxahachie.

Dang, you guys get to see all the cool stuff in Europe! I'll get there one day. Get yer beauty sleep tonight Stefan!!!!!! :-) S.W.

Reminds me of a good part of the pipe welding we did inside nuclear submarines when I used to work A EB. ;) :) :) However, we were usually entangled like a contortionist in between many different pipe or tubing lines while welding in all sort of positions!!!;) :) :)

"Mirror, Mirror on the wall," or pipe or gusset, or in my hand, or whatever else was holding on to it... "Who's got the greatest hands of them all!!!" is what I used to mumble when I welded with either one, or more mirrors in order to complete the joint I was assigned to...

These days, I don't hum that tune anymore because in truth, those days are long gone. :( I mean I can still weld with a mirror, or two, or three but, I'm not the one with the best hands anymore! ;)

Respectfully,
Henry

Henry,

Steve,

yes... I would like to agree with you!

This stuff is absolutely unique in the world and I ask you to believe me, it was one of the most impressive and most sustainable experiences in my life to have been there!

I got there due to Alex - a PhD mathematician - who is a good friend and colleague of mine. He again has a former fellow student, Martin, who has studied phyiscs and did his PhD in Vienna at the "Atom-Institut". Since Martin is a good friend of him again Alex was invited to visit the Compact Muon Spectrometer (CMS) before it was "closed" by connecting the ring and all its "bowels" would have dissappeared behind tons of tons of instruments and insulation.

By the way, Martin, the physicist, told me when I got to know him at that time, that Alex has prepared the math homework for him and some other physic students. But that was stopped promptly that day as the Professor has asked them, the physicists, how they have resolved the most complex differential equations in a way that even the Professor himself was surprized about! That was the day, Martin said, when they have begun to do their math homework by themselves again... :-)

You know, I do honestly admire these colleagues since they are blessed by the Almighty to understand things which are that far above my head that I feel giddy when I am just thinking about! Martin is with the CERN one of the responsible persons for the "counting of the particles" after a collision has occurred. May God forgive me this simplification but I have never seen so many Personal Computers!

However, Alex was - as he knows my true passion for physics and this "stuff" - so kind to ask me that time to accompany him. And as
I said it was... words still fail me.

Please let me attach some pictures which I or we respectively, have taken at that time.

And Steve... as you say: " I'll get there one day.".

Please do it! This is my humble but very true and most friendly recommendation. :-)

Best regards,
Stephan

I enjoyed the pictures and "the notes" on the pictures....
Parent - - By Stephan (***) Date 08-04-2008 11:25
Aaahhhhh John,

once again, you're making my day!

Thanks a lot my friend!

John!

Excellent Video!

Thanks for the link!

Hmmm... sweet sweet memories! :-)

By the way, as the first fellow spoke of the electrical signals being transformed from the collision particles and subsequently detected in the counting room.

This is where Martin is working at and this is where the tremendous plenty of PC's were installed on the level above the counting room. They are to perform the counting and processing and analyzing a particular fraction of the entire - quasi infinite - data.

I have found some more pictures showing first a section of the PC's, installed as mentioned above. The second is showing a bunch of cables connecting the computers with instruments - from where ever they may come from :-). And the third picture shows one of the ends of even the bunch of the leads. Namely the connector's side, waiting to be connected to some other instruments. Heaven knows what kind of instruments they are plugging onto these connectors... :-)

Thanks again and best regards,
Stephan

Henry......My head is spinning. Kinda like ultra hardcore fusion-metal jazz in off time. :-)

Cool stuff!

Parent - By Stephan (***) Date 08-05-2008 14:22
Henry!!

Good heavens again!

Where do you get all this stuff from?

Once again you're blasting away my tiny brain!

Thank you so much for sharing these great information with the Forum!

It will certainly require lots of patience for me to struggle through this bunch of excellent literature.

Therefore I must unfortunately say Good Bye to the Forum now for the next... hmmm... 6... 24 months?* :-):-):-)

Or to quote Steve: "You sunk my battleship!" :-)

All the best to you as well, Henry!
Stephan

No, thank YOU.
I work with computers, and those bundles of pictures of the nicely color coded (all black) wires with identical connectors just made my day!

Thanks Robert!

Hmmm, good feeling to have contributed somewhat that has made an appreciated fellow's day! :-)

Stephan,

Neat picture, but the guy needs a lesson in welding safety.
Parent - - By Stephan (***) Date 08-04-2008 11:23
Gerald!

Besides all this "glory" one could almost assume that they show no mercy with the welders... :-)

"Weld you curs!! Weld until the first one drops!!"

Or... in other words... "Weld with the gloves off"!

Who else - if not you - would have considered this?! :-):-):-)

Of course you are... absolutely right!!

Best,
Stephan

this is all rubbish!
here's what the LHC is really doing
http://www.youtube.com/watch?v=Lt1Yo610lG0

just kidding, that guy is crazy but he manages to wrap just about every conspiracy into one, so kudos.
there's lots of conspiracy theories about LHC and CERN, I wonder why that is?
Parent - By Stephan (***) Date 08-08-2008 13:15
Hmmmm...

Hard stuff!

P.S. "... there's lots of conspiracy theories about LHC and CERN, I wonder why that is?"

I would have never thought what's all contained about the LHC project with youtube. I guess this machine has a little more power than a stony hand axe, so let's pray that the smart people over there may really know what they're doing :-)
