Europeans have the coolest backyard parties.
“The Welding of the Rail” is an old favorite, usually when the host runs out of beer.

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.
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
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.
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.
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.
Gentlemen. I love to see Professionals at work. This is as exciting as anything I've seen for some time. Thank you.
Nice video. Cool to see the process.

I agree
impressive
:)

After half an hour perhaps...
this was oddly satisfying to watch
Danke fürs zeigen...hatte ich so noch nie gesehen!
man these RC machinery construction videos are getting impressive!
I have to say that the crew really knows what they are doing even if they are not talking to each other
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!
Interessante Technik und ein wirklich interessantes Video. Toll, dass du das Aufnehmen konntest. Daumen hoch. Gruß Unimedien.
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 !!
German tradesmen have a hammer for every occasion lol!
Well now THAT was cool as ever. Love how things get done.
Jesus friends world
.. das war jetzt mal echt interessant anzusehen! Danke! :-)
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.
i love tools & this kind of work. thanks
10 feet of track complete. Well done fellas. Just 1100 miles more to go
Que nivel por favor!!! Excelente y felicitaciones por el video
Wow, I can finally weld my railway, thanks guys
....und alles so genau erklärt! Toll.
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.....
Zauberwerk Toll!@@!
Sonnenaufgänge sehe ich auch wo anderst !
I don't remember clicking on this video. I don't know how I got here. It showed up as one of my tabs
RUclips 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!
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.

Great video....& resolution. Learned a lot about the process of thermal welding.... Thank you for your effort to post and share....
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.
Schönes Video👍✌ von denn Dewind D4 🗽NewYork Tobi🗽 ich bin immer überall dabei weil jedes Video interessant ist!
nice vido - more like casting.
Fascinating!
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.
They're building a tramway in my city, I was lucky enough to see this happen live this summer.
Wirklich sehr interessant anzuschauen.
Great video, so interesting, thanks for sharing
Wow... Excellent
Mit Abstand die spektakulärste reperaturarbeit an Gleisen
Schienen werden immer geschweißt oder durch Laschen/Iso Stöße verbunden. Ob Neubau oder schienenwechsel.

,ich danke sehr für die Vorführung das war echt interessant !
Very nice video !
Aluminothermy, I learned that at school when I was a kid !
:o)
Good job
Thermit ist schon was schönes..
hexlgaming Jup definitiv
They've got some cool tools.
That's a lot of specialty equipment
No idea how I got here, but that was great.
Interessante Technik, auf jeden Fall eine heiße Angelegenheit. Daumen hoch fürs zeigen! Gruss inselvideo!

Danke dafür! Mein Urgroßvater hat an der Eisenbahn gearbeitet.
fine video.....
0:32 Wenn ich meinen Traktor vorglühe... (when I warm up my tractor...)xD
That hydraulic rail scraper slag chopper is sweet
Oct. 30, 2018---Thanks for an interesting video, but wonder how long in real time did this take vs the shortened viewing time.
Imagine how interesting this would be if there was a narrative of everything that's involved.
More involved and critical than I ever thought. I'm surprised the ties didn't burn.
i have no clue what i just watched but it def was worth it
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...
Did thermite welding to ground wires welding in a electrical substation once. Pretty cool.
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?
Cool, but it leaves one question unanswered: How and where do welded railways allow for thermal expansion and contraction?
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?
Impressive !
They make it look so easy.
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. ^^
Sehr interessant sowas mal zu sehen.
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 !!
All that for 1 joint. Each joint 33 feet apart. For 150 miles. With two rails. "Ok guys, only 47, 999 more to go. "
Das war sehr cool
Now that was cool
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.
I thought rail road tracks should not be welded or bolted together with fish plates too tightly, to allow for expansion?
This seems extremely tedious for what you get from it. Does it have a better lifespan than if you just used an arc welder?
I don't know the answer but puddle arc welding seems to be more common for crane rails.
We used to use the over flow slag to boil our cast iron kettle for a brew up while waiting for the setting time
Wow! Some jobs are just funner than others.
mmm delicious homebaked iron cakes
Long work hard work, nice video.
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.
You’ve done a mans job sir 👍🏻
Hab das gerade in chemie. Danke fuer das video
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.
Hut ab! Die können was!!
What we don't know is how long the rails are that they are welding because rails are welded at the shop in great lengths and then railed to be laid. I'm sure we're not talking short length rails here.
Wow, never knew termites where flameable :/
lol, its a chemical called Thermite not the ants...
Yes that is true. That is why the British government refuses all fire ant passport applications.
It is thermite
Gus at my local welding shop said "I use termites on my steel projects but I don't have any luck with them on any of my wood projects."
:|
Did they just bolt the rails together before this or bring a portable welder out?
how much I work for nothing ... when he realizes that the track is disconnected from the railway track, he will be very long
bad :D
schönes video gibts die schnallenschuhe nicht mehr ?? hätte die zw noch entfernt aber sonst klasse wie im lehrbuch lol
Respekt... also das hab ich auch noch nie gesehen...
Good job ))))
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
Amazing demonstration but in a real weld the slag has to be left longer to allow a slower cool down
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 ?
super
Looks nest however I wish someone explains what they are actually doing don't understand what the yellow buzzing machine us I assumed it was a x-ray checking outcome the weld has penetrated.
now when there were fishplates there were expansion joint, where have they gone?
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.
ruclips.net/video/5d5iIoCiI8g/видео.html
Nice video.
Welld one!
:-)
I have welded everything for 45 years, never saw this before.
So would they do this on every single joint? Seems like a long repetitive process for a whole railway
Muy bueno :) :)
