Railroad thermite welding

[@scrembirb6685]

so many steps, tools, and time to do just one, cant even imagine doing an entire road, mad respect

[@tastenheber]

I would imagine, that there are bigger machines, which make the process a lot more comfortable and faster, but they maybe too expensive for just „some“ joints.

[@kilianp.5692]

I guess that's why railroad construction usually takes such a long time

[@katanamaki9015]

When laying down new rail there will be several crews working on welded joints simultaneously. A dozen crews or more could complete several kilometers of rail per day.

[@yisakii8397]

I thermit weld now for almost 4 years and i can tell those guys are experienced even tho you dont see how they prepared the rail for the actual welding process. Like cutting the necessary gap with a flame torch and setting the rails even with almost zero tolerance. Hats off to anyone who survived this job for more than 1 year. Even tho you see the "actual" work done its also the easiest thing about the day. But carrying this heavy equipment to where the rails have to be welded is the hardest part for us. Sometimes we push it on a wagon that fits on the rail tracks miles since u cant reach it with the working car & if you have a bad day you have to push it uphill. To this day its always a challenge, for all of us. Guys who looked like the rock quit after 1 week saying its too hard for them. This job exposes men that thought they are the toughest. Having and finding the will every single day is what keeps you welding rails no matter how tough you are. So if anyone looks for challenge i can recommend to go for it. The treat you will get is good money and back pain really fast x)

[@jpal00]

@@HourTruth The temperature is changing throughout the year, therefore the rail has to be clamped to the sleepers really tightly so it doesn't move. When it is hotter the rail is under pressure, when it is colder, the rail is under tension.

[@davidrichards8639]

Fantastic, I studied this process 50 years ago as a welding apprentice but never saw it before, this joining of railway lines was the only application it was used for then. For those that do not understand welding, it is still done today as before because while the set up is slower the overall process is faster than a manual process, the rail contour would be a pain to manually weld and dam. Thermite welding deposits a very high quality weld and not to forget this is a "Hatfield Steel" an 11 - 14% Manganese steel, not so easy, except of course to you experts out there.

[@westlock]

David Richards I thought that they used flash butt welding for rails.

[@simonross4281]

Howard Glen Flashbutt welding is used in the manufacture of long lengths of welded rail, but when it comes to joining those lengths up in situ it's usually thermite welded

[@davidrichards8639]

***** To flash butt weld these rails on site would require them to have their own electrical sub station, the KVA requirements would be enormous.

[@simonross4281]

David Richards Not so, there is mobile rail flash butt welding machinery available, it doesn't tend to get used much because difficulties with track access, availability and cost all tend to favour aluminothermic welding currently.

Now you just lift the yellow cutting machine (what you see in the video after they welded it) and rip the steal off without damaging the weld. It saves lots of energy and time for everyone.

[@MrWolle1950]

[@sik59rt]

Wolfgang Lendner even with more ballast in b/w there, those ties seem a lot larger then what i normally see here. is the track gauge any different too?

[@MustObeyTheRules]

Maybe because this particular rail road is meant for heavier and faster moving trains ? Idk just a guess.

[@ThrashForceOne]

sik59rt The track gauge is mostly 1435 millimeters here in sweden, but we have a couple of active tracks (Roslagsbanan, for instance) with the older gauge of 891 millimeters. On Inlandsbanan shown here (which is not part of the regular railroad network) they mostly have tourists and residents travelling. I'm not sure what the max speed is because it differs due to location, but the trains can make it up to 130 km/h.

[@machia-mw1lm]

Isn't this before the ballast ? You have to surround ties whether concrete or wooden to prevent shifting I would think. Unless the concrete ties are so heavy they require no ballast, but I doubt that is the case. Interesting video.

I Thermite Welded for the CNR back in 1981-82 (then Joint Welding and Magnesium Frogs). It was very similar to this video except for the crucible. Ours were much more antiquated ! But the Molds, Shields, Slag Pots and Packing Paste appear "almost" identical. We used Hot Cut and Sledge for knocking the over-welds off but eventually were rewarded and equipped with (what appear to be the very same) hand-powered Sheers and ultimately Powered Sheers.

[@high1voltage1rules]

Why didnt you show the track after the finish?? what was being done? No one said a word?

[@HauntingBull]

I will explain. 1) There is a clamp in place to hold the ends together as he heat treats them. This clamp also acts as a guide/holder for the thermite. 2) They use the thermite to bond the two ends together using the heat and pressure generated. 3) They remove the apparatus and clamps then proceed to knock off the slag (waste material) on the outside while it is still hot and brittle. 4) All that's left is for it to cool (which takes a while) then polish out any rough spots and check the quality of the weld. You can see a finished weld behind them if you look closely enough. Hope that clarifies things for you. :-)

The extremely specialized equipment (this ain't your body and fender spot welder) and the procedures that have become second nature to these rail workers is what is impressive to me. Curious what the dollar per hour wage would be for this type of work. Thanks Mr Lendner for the clip.

[@adamjackson9988]

What happened at 0:48? Whats that pop, the track moving from the heat?

[@BlackWolf42-]

What was the 'twang' sound at 0:47? Was it due to a piece expanding or what?

[@IhateYoutube]

The molten metal dropping from the bucket hitting the much colder rail, the rail amplifies the sound because it's so long it acts like a tuning fork.

[@Fakhrealammm]

brett248vista wow thats a great answer. thumbs up

[@IhateYoutube]

fakhre alam Thnx :)

[@sidedoororiginal]

brett248vista No, that wasnt it. I am a railroad worker and i recently worked with the team welding the rails together in exactly the same way, and it never made that sound. The sound either came from someone hitting the rail nearby (You can hear someone hitting it with a hammer from quite a distance if you are standing close to the rail) or from someone splitting a rail in two (We had this happen, because we were removing a 5m long piece of rail, and then welding a new one in its place, and when it separated, it was under big stresses, it would snap out of place slightly, making that sound.)

[@sidedoororiginal]

brett248vista You can see the guy in the back, he hit the rail with the hammer, if you look closely. Rails are finely aligned on two ends, with hammers. You can only get them so aligned by placing them and pushing them around (Takes A LOT of people to do this) and to move them such small amounts you hit them with a hammer/sledgehammer.

Intense????? You can’t be serious.

[@Icza]

They're putting in a new rail beside my building right now. I was wondering after seeing the separate rails that all appear to be one long rail now, how they fused them so perfectly.. I came across this video randomly without searching so that was a nice coincidence. Anyway, very interesting!

[@butchphaneuf9675]

How long would an experienced crew like this take to do one weld, including prep? Always appreciate seeing experts do what they do.

[@jepolch]

Very interesting. I didn't know that the rails were welded together.

[@timdickson5531]

The sound effect for the laser blasters in the original Star Wars movie was created by hitting the steel cables of the Severn Bridge (a suspension bridge in the United Kingdom, across the River Severn) with big wrenches (or spanners if you're British). So I guess twatting a train track with a hammer makes a similar noise.

@@johnnymnemonic69 I thought I heard the clickety, clicks of a train on the track.....🤷‍♀️

[@Dessme]

I learned that the joints are there for a reason - to give space for the expansion of the track due to heat. Now if you weld them you are preventing that mechanism and would probably result in a twisted track. Not sure if I am right though. I like the sound of the joined tracks which gives some kind of drum sequence. But some are a bit noisy and would prefer a silent one.

[@mooneyes2k478]

All rails have expansion joints. Doesn't mean that each rail piece have to have them. CWR(Continously Welded Rail) runs for kilometers between the joints. Also, expansion joints don't run that way(90 degrees to the rail), they are diagonal and far longer.

[@Dessme]

@@mooneyes2k478 But as I watched several train videos, I usually hear the sound the train makes when passing those expansion joints but some trains, You don't hear that sound which made me conclude it is soldered all the way through.

Spiez-Zweisimmen isn't, it's more or less a commuter train with a distance of 35 kilometers, approximately, that is running in Switzerland, a country with somewhat...Germanic....levels of accuracy and infrastructure.

The coolest part about the new way of building tracks is what the end of them look like. On the boston t, in the winter there's about a 1/4 mile, if not more of unused railroad ties at the end of the line, in the summer there's almost none left cause of the expansion of the tracks.

[@randallstevens5433]

For some reason I love the complexity of that yellow small thing they put on the rail. Looks fun to play with.

[@simonross4281]

+Monel Funkawitz Someone else hitting the rail with a hammer further up the track, probably one of the other team of welders you can see in the distance.

[@GyprockGypsy]

That sound is created by vibrations traveling down the rail. The rail is shaped like an H, and the two "high points" (in relation to the H) act like a tuning fork. A really long tuning fork. So, instead of the vibration just getting passed back and forth between the two tongs of a tuning fork, it gets passed back and forth, and down along the track, making the sound travel away. I know it's not the simplest, or clearest explanation, (or punctual) but I hope it helps answer that question.

[@TheeArson]

Monel Funkawitz it sounded like a laser

[@kurtiskaskowski5386]

[@tdc8795]

That track was glowing like the steel beams they recovered from WTC 1 & WTC 2. Could thermite have been involved then too?

[@MatthewChapmanSTL]

I'm always amazed at the number of construction workers who won't wear protective gear for their own safety. Why do they even have to be told? Don't they value their sight/hearing/body enough on their own to want to protect it without needing to be told to do so? Stupid...

[@gearsNtools]

Maybe the lack of forward thinking is partly why many of them are in construction. I'm in construction and I see a lot of not so bright guys who fell into the trade since other opportunities were wasted. not always the case but it's more common than you would see in an engineering office.
