Europeans have the coolest backyard parties.
“The Welding of the Rail” is an old favorite, usually when the host runs out of beer.
lohphat
A classic! 🍺
Unst Velding party bring beers uns schnitzel!
Yeah, and we grill our Bratwurst directly on the thermite bucket.
Bloody good show!🙏
last summer we did this, it was a great evening for the whole family. The thermite roasted Bratwurst mit Senf im Brötchen was more than delicious!
For me as a frequent rail traveller in Germany, this has been most interesting! Thank you for uploading.
In 1970, I worked for a company in the UK; Murex Limited, who developed the Thermit welding process together with a German company; Elektro-Thermit GmbH.
At the time, there was widespread rail replacements being carried out in the UK, and the Thermit welding process enabled sections of the rail to be welded in situ.
I worked in their analytical laboratory in Essex, and one of my jobs was to check that the constituents of the mixture was correct. I remember that we were given a demonstration (similar to this) on how the process worked - pretty spectacular! The process is still used, not only for railway lines, but for welding other large items, such as ship anchors.
I'm working at the depo station in Stuttgart, Germany and never saw this before, so I was really shocked when I saw flames and something on fire on the other side of the station in the middle of the night. I was close to call the fire department when I got the info "Keep cool, they're just busy with rail-welding" :D
this was oddly satisfying to watch
THAT WAS AWESOME! I have only ever heard about this being done by the old timers. I never thought I would ever be able to see it done! Thank you so much!
In case anyone wonders: This was a demonstration at the Hannover Tramway Museum at Wehmingen near Hannover in September 2017.
Ah okay makes sense now. Was wondering why all the high techniness of welding rails together but still using wooden ties.
nobody likes a smartass
@@gewizz2 that was so unnecessary
In Alabama?
@@BlackMeowgic like Rekowagens comment.
I have to say that the crew really knows what they are doing even if they are not talking to each other
Nice video. Cool to see the process.
Maryland Construction Diecast v😈😈 😇🐑🎒🎒😇😴👠👢
I agree
impressive
:)

After half an hour perhaps...
That was one of the coolest things I’ve seen in quite a while. I had no idea that was ever done to begin with. Great stuff.
Danke fürs zeigen...hatte ich so noch nie gesehen!
I see that's at the streetcar museum near Hannover, Germany. Great place to visit.
God they got a freaking tool for everything
Richie Mann They build thousands of km of railroad using this method. So the process has to be perfect and quick.
Germans. nuff said
using termite to weld it removes the possibility to have an air pocket inside the weld, and its just faster
Yes. No need for heroics - work smarter not harder.
757WN - think of how much heat a railroad track can absorb !! It’d take days to pump enough heat into the system to weld it whereas here, you dump a *_massive_* amount of heat into it *_fast_* so the thermal mass of the track doesn’t have time to sink it away !!
Gentlemen. I love to see Professionals at work. This is as exciting as anything I've seen for some time. Thank you.
man these RC machinery construction videos are getting impressive!
10 feet of track complete. Well done fellas. Just 1100 miles more to go
....und alles so genau erklärt! Toll.
Interessante Technik und ein wirklich interessantes Video. Toll, dass du das Aufnehmen konntest. Daumen hoch. Gruß Unimedien.
Thermite welding is awesome, what a great process. We made a thermite reaction in high school, I can still see the molten iron dripping out the bottom of a terra-cotta pot in my mind, even though it was nearly 30 years ago and I never bore of watching this!
Al t You mean you did and learnt real stuff at high school? Wonderful
Al t
The molten iron was dripping into your mind? That’s not good!
Well now THAT was cool as ever. Love how things get done.
Jesus friends world
Wow, I can finally weld my railway, thanks guys
.. das war jetzt mal echt interessant anzusehen! Danke! :-)
i love tools & this kind of work. thanks
German tradesmen have a hammer for every occasion lol!
Das sind klasse Aufnahmen, sehr interessant anzuschauen. Daumen hoch dafür!

Wie hoch?
What are you saying?
Wie hoch = how high. Daumen hoch = thumbs up, Just asked how high they put their thumbs up.
Did I just watched 7 minutes of rail welding???
No, your clock must be wrong.
What is wrong with watching thermite welding? It’s a whole lot more educational than watching Spongebob.
yes, this is the way most males spend our lives.
I suppose it all comes down to have given up on hope of finding women.
iannickCZ Yes
When you realize how much time you waste on stupid random bullshit you won't ask yourself this question anymore. And at the end of the day it doesn't fucking matter what you do/watch. Variety and randomness make life a lot less borinh. As Forrest Gump once wonderfully said: "Life is like a box of chocolates. You never know what you're gonna get."
Wait, did I just spend several minutes answering a random comment on a rail welding video? Oh well.....
They're building a tramway in my city, I was lucky enough to see this happen live this summer.
Que nivel por favor!!! Excelente y felicitaciones por el video
Zauberwerk Toll!@@!
Sonnenaufgänge sehe ich auch wo anderst !
nice vido - more like casting.
Wirklich sehr interessant anzuschauen.
Mit Abstand die spektakulärste reperaturarbeit an Gleisen
Schienen werden immer geschweißt oder durch Laschen/Iso Stöße verbunden. Ob Neubau oder schienenwechsel.

I don't remember clicking on this video. I don't know how I got here. It showed up as one of my tabs
UA-cam Autoplay? 😀
I have already made the same experience.
I think it's because you're an idiot
how the fuck did i get here
You should control your computer rather than it controlling you.
It's another thermite related conspiracy!
Great video, so interesting, thanks for sharing
Fascinating!
All BNSF track, throughout the U.S., is welded together this way. It is monitored for breaks constantly this way. A continuous track is essential for the speed and weight of the trains traveling on it. This is also how the signal lights are controlled. The same may be for other train companies.

They've got some cool tools.
,ich danke sehr für die Vorführung das war echt interessant !
Wow, that's way more involved and time-consuming than I thought it was. But considering rails can be in-service for decades, I suppose it's a relatively tiny amount of effort for the added benefit of having a smoother rail.
Not just smoother but safer.
@@EvoPortal when done wrong this method has the potential to be far more destructive so I wouldnt plainly call it "safer". Ever heard of thermal expansion? Imagine a km long rail expanding. those things need to be calculated and thought of in advance otherwise you'd have rails bending all over the place in summer.
@@chriseffpunkt4333 You are incorrect. Statistics prove you very VERY wrong.
Great video....& resolution. Learned a lot about the process of thermal welding.... Thank you for your effort to post and share....
Very nice video !
Aluminothermy, I learned that at school when I was a kid !
:o)
Thermit ist schon was schönes..
hexlgaming Jup definitiv
Interessante Technik, auf jeden Fall eine heiße Angelegenheit. Daumen hoch fürs zeigen! Gruss inselvideo!
inselvideo i
More involved and critical than I ever thought. I'm surprised the ties didn't burn.
That's a lot of specialty equipment
No idea how I got here, but that was great.
Schönes Video👍✌ von denn Dewind D4 🗽NewYork Tobi🗽 ich bin immer überall dabei weil jedes Video interessant ist!
That hydraulic rail scraper slag chopper is sweet
All that for 1 joint. Each joint 33 feet apart. For 150 miles. With two rails. "Ok guys, only 47, 999 more to go. "
Danke dafür! Mein Urgroßvater hat an der Eisenbahn gearbeitet.
Did thermite welding to ground wires welding in a electrical substation once. Pretty cool.
Was für ein Aufwand für eine Schweißnaht, da schaffst du ja gerade mal 20 Stück am Tag, aber schön anzuschauen war es allemal, danke für's Einstellen.
Wow... Excellent
Good job
They make it look so easy.
i have no clue what i just watched but it def was worth it
fine video.....
You’ve done a mans job sir 👍🏻
Hab das gerade in chemie. Danke fuer das video
Wow! Some jobs are just funner than others.
Imagine how interesting this would be if there was a narrative of everything that's involved.
Sehr interessant sowas mal zu sehen.
mmm delicious homebaked iron cakes
0:32 Wenn ich meinen Traktor vorglühe... (when I warm up my tractor...)xD
Sieht nachts noch besser aus. Glaubt mir!
In der Praxis wird auch besser geschliffen :D
War das hier nur in der Theorie? Sorry, ich konnte nicht anders. ^^
We used to use the over flow slag to boil our cast iron kettle for a brew up while waiting for the setting time
Impressive !
Das war sehr cool
Hut ab! Die können was!!
Looks like so much more work than the old way, with bolts and plates, but I'm sure this type of joint is much more solid and needs much less maintenance.
Long work hard work, nice video.
Nice video.
Welld one!
:-)
Wow how welding has changed, now you could weld that in 10 minutes or less, neat to watch*****
DJ GTO Thermite welding is still the standard today in railroad building. Just because it is easy and quick.
also as long as the rails are aligned properly gap doesn't matter and from what I hear when it comes to rail repair over time that can be a big problem. Wish they would let us play with that stuff in the shipyard.
DJ GTO - good luck welding this... look at the size of a railroad track, you would spend a week pumping heat into it to get near welding temps as it’s thermal mass would sink it away no problem. With this method, you’re dumping a *_massive_* amount of heat into the system too fast for it to sink away !!
Respekt... also das hab ich auch noch nie gesehen...
Now that was cool
Think how many miles they have to do this for. I wonder if there's a more streamlined process when they do it for real or if it genuinely takes that long...
Oct. 30, 2018---Thanks for an interesting video, but wonder how long in real time did this take vs the shortened viewing time.
Супер! Так много операций,и все так аккуратно! Жаль что в России ,так никогда не будут делать!
В россии так уже больше 10 лет делают)
Fascinating. What is the material around the iron? Is it a clay cast? Also, does the weld now consist of cast iron or are adjuncts in the thermite to produce a sort of steel?
Heisse Sache! Sehr interessant, ich kann nur die Termit Sprengschnüre, die dicke Stahlträger durchtrennen für eine Häusersprengung...Gruss DrDuu
wie die WTC-Tower, you know ?
Wow, those are almost like the thermite box cutters they used in the world trade center attacks.
Yes - the very same, the Thermite cutters used on all three buildings were set upright around all the main support columns to create a sloped cut, the military developed thermite was ignited with demo fuses.
Хорошая работа
Cool, but it leaves one question unanswered: How and where do welded railways allow for thermal expansion and contraction?
*A REALLY BIG FUCKING WELD, COMING RIGHT UP*
Strongest joint I’m sure but wow does it take a long time to do one. I couldn’t imagine having to do miles of it. Makes me want to look up how they did it in the old days
Modern rail tracks are not done that way, just a demonstration from when it was.
Does the aluminium oxide by-product effect the strength of the weld in any way? Or does it form some sort of slag that floats to the top of the weld?
Good job ))))
TOTALLY FASCINATING! ... I walk my dogs along the railway tracks in Toronto and many times I've walked along the rail trying to find a seam but NOTHING! .... FINALLY I KNOW WHY! .... (....thanks for that AND for showing us EXACTLY how the Israelis imploded the WTC Towers on 9/11).
Escaped insane asylum patient alert (Mark Marsh)
To the 337 dislikers: Let's see you do it any better ;) Seriously tho, awesome work, nice video :)
Amazing demonstration but in a real weld the slag has to be left longer to allow a slower cool down
Saw this done in 1984 with a military thermite grenade. a demonstration of a combat weld by the DB for the US Army
We all know that tons of NANO-thermite was used in the New York twin towers on September 11 2001 to cut the many steel beams in short, transportable lengthes.
Watch this video that proves it.

Pretty short train line.
it was for a miniature railway set
It's a very small museum ;)
People are smaller in Europe.
That would be the "express" rail line
I thought rail road tracks should not be welded or bolted together with fish plates too tightly, to allow for expansion?
super
Hello Welcome, don’t worry your not alone, all of us are here also don’t know how we got here or why we are watching this. Yes none of us searched for this either but here we are
...and at the very end of the video, a supervisor walks over and let's them know that this was the WRONG piece of track.
I'd pay a dollar to see that!
There is welded rail in North Austin. A machine the size of a locomotive grabs and lifts the ties, fluffs the gravel and reseats the ties level as you please.
Did they just bolt the rails together before this or bring a portable welder out?
cool I liked it 👏👏 🇧🇷
Did this in high school ! FUN !!
