![Rails thermite welding - Eruptions, melt squeezing and grinding [4K]](http://i.ytimg.com/vi/rNjosF789X4/mqdefault.jpg)
For those who are unfamiliar with the Thermite welding process, the red powder @ 1:31 is Foundry Sand which is used to seal the gaps around the mold. The grey powder @ 3:32 is Thermite which is a mixture of powdered Iron Oxide + powdered Aluminum. @ 4:25, the mold is preheated. @ 5:30, the Thermite contained inside the bucket is ignited. The high heat from the exothermic reaction produces molten iron which flows down into the mold. When the iron has solidified sufficiently, then the excess flash from the mold is ground off to make level and smooth the now repaired joint in the railway track.
Thank you!
Underrated comment :)
Thanks for kind information 👍
Wouldn't it just be easier to change out the rail(s) or is it ribbon steel?
@@vaughnmcmillan8400 this is just the way, how a changed out rail is joined into the track
Always wondered how they did this. I retired from the railroad and think the track workers are one of the most important assets of the railroad!
this was SCAM WORK ( totally unnecessary - to make extra money)
The could have just measured and pre cut the right size

Makes you wonder about the quality of that thermite weld. Soon, there's going to be a train with 500 people riding on the roof doing 60mph coming.
Simple tech and it works. It’s used in Australia too - simple and reliable.
Технология не плохая но у нас в России из-за климата лучше сварочный поезд ,но по цене и времени затраченного конечно не сопоставимо с термитом
I welded for 50 years....this never ceases to amaze me
Excellent result.
Thanks for the upload.
Great to see professional repairers in the field.
and their safety footwear !
'professional repairers'

Beautiful job

Persze, van ellenálláshegesztő gép, de a záróhegesztéseket a mai napig thermittel szokták végezni. Vagy például kitérőknél nem is lehet ellenálláshegesztővel dolgozni: nem fér hozzá. Szóval nem primitív módszer, megvan a helye a vasútépítésben.
It is not primitive, in USA and some European countries this method is still in use.
In wintertime the men was pleased to be near the welder's to keep warm honest
Ex rail worker worked in subzero temperatures
Blizards
Storms
Extreme heat...
And when cooled down enough, the slag made a good hand warmer, just be sure to wear your gloves 😉
Well Done. from Ireland. GT Video 😊🛤️🛤️🚆
Put on Again met some Indian guys for few few beers lately twice. 😊 Enjoyed tr Company. From Ireland
The sneakers say it all, safety first
Mi hijo trabaja eso en España y es un trabajo muy delicado y de responsabilidad bendiciones para todos 🇩🇴
Why aren't they wearing safety boots and gloves, eye protection and high visibility wear in case of oncoming trains ? Clearly the Health and Safety of workers such as these is of low priority. I just hope the trains themselves are safe to use !
This is most likely in India
Florida or Texas

Excellent video ! 👍
'Been there, done that' forty years ago! I was a track repairman for SEPTA in southeastern Pennsylvania.
itu bantalan rel kudu ada di bawah pas sambungan untuk memperkuat tekanan di atasnya,,,,gitu lho.....😊
The last one I watched of this crew, they were sledgehammering of a piece of slag and cracked the weld right in two.
The satisfaction of this video 💯
This is must from India because there are not wearing hand gloves and safety shoes 😂😂😂😂😂😂😂
Super dosto....

Try commercial jet fuel, I heard that works well too.
Nah, that just weakens, doesn’t melt.
It was an Inside job m8. Americans were in bed with the Mujahideens, remeber?@@WashashoreProd
enclosed and large enough it will
fingers and hands are versatile tools😌
Stumbled across this. Absolutely captivating.
wow, very manually intensive
Boa noite! Inscrita no Canal!! Belo flagrante!!👏👏🚂🙋♀️
Good invaluable work 👏👏
Great job!!!!! they must be proud people!!!!🤫🔴🫢
I had fun with Thermite welding in the 60s.
I was doing that thru the 90's.
It was used on Sept. 11, 2001.
YES, this process has been around for a very long time.
At 7:22 ...removing the mold ....molten material pours out. There IS a documented ENGINEERING procedure on this entire process from beginning to end. I wonder how long the "cooling" time is BEFORE the removal of the forms. I would expect that ALL the molten material should be cooled enough to be in a "solid" state BEFORE the removal of the forms. In most ALL casting processes, "extra" material is used to "feed" a cavity during the cooling period.
In order to know the answer, the Engineering Procedure needs to be known.
Typical previous comment is nothing more than a generalized overview of the process. Nothing detailing this "cooling time" .....just "When the iron has solidifies sufficiently ...". I would NOT be surprised if this joint has NOT cooled long enough.

Thank you for uploading the video.
Wow there seems to be what looks like molten metal pouring out the side of the building.
Seen something like this done with copper rods for grounding, deadly fumes.
Same exact thing happened to the steel on the twin towers in New York when they collapsed.
Impossible, thermite can't melt metal, saw it on Mythbusters🤣🤣
@@hansemannluchter643Google it, thermite is used for cutting or welding steel, I would stay away from myth busters.
It’s true. All metal has the same melting point. Mercury, steel, tungsten, it’s all the same!
Great work 🎉
Great great work
This vedio is from India !!
same color temperature seen on the sparks on the side of the TWC before they collapsed
Always use safety shoes when do this repairing works.
I am from Algeria. I worked in this field on the railway for five years with a private company, then we stopped after that. I want to continue this work in a state-owned company, and when I asked for my rights at work, they sent me to court 🤔🤔
Das sind die Fachkräfte die wir in Germany brauchen . Von JJE Germany. 😢😢😢😢😢😢😢
Glad to see they aren't out there doing that wearing their flip flops and gym shorts again .
This isn't happening in the US. Wherever this is in the first 30 seconds there are code violations happening all over the place. Railroad company managers and supervisors get a little testy if the line workers are not wearing steel toed boots and are wearing shorts. Insurance inspectors jack rates through the roof where they catch that.
Yeah, the lack of safety is insane
thermite welding for train tracks? That’s some serious heat! 🔥😅 I wonder how many safety protocols they have to follow to make sure things don’t go up in flames! Would you trust a welding guy with a torch that hot? 😂
That makes sense, saw a rail just to turn around and weld it again.
The rail they welded wasn't the same one they sawed. They sawed and removed a damaged rail then replaced with a new rail and welded that.
Even a blind man can see that the rail being welded into place is a new rail. Not rocket science is it?
@@modelsteamers671 The new one is rusted out. Even a blind man can see that.
@williambryan356 of course new rail is rusty all new rails are. The passage of wheels clears rust from the railhead one it is installed and in use.
It's always great. We liked and enjoyed to the end. Thanks
Why the railway management is not looking for the safety of workers they are working without PPE and some activities require appropriate PPE. It's a very serious issue.
1:44 their are speaking hindi language it might be our india or Pakistan. ❤❤❤.
응원. 합니다🎉🎉🎉🎉🎉🎉
AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! tx for sharing!!! :D
Very good jobs
I saw for the first time that the welding was completed without removing the tracks.
Ndokubasa!! From earthworks, sleepers installation, ballasting and rail alignment.
Note they have to grind the rail smooth. If there's an imperfection even as small as a penny on the tracks, the train will derail.
The usual to deal with armoured vehicles. Sludge-oil/crude-oil to stick to tracks and vehicle, diesel to stick to sludge, petrol to stick to diesel, thermite touch is classy-art.
Thermal detection of metal and emitters...
Hunt armour, army, ships, ...
Wes luar biasa amazing
Oh, so they were only trying to STRENGTHEN the twins and WTC 7 when they used nano- thermite on 911! Gotcha. 😅
Booooo.
They didn't use thermite in the 9/11. Search Judy Woods speech in 2011 "where did the towers go"

when the form was knocked off the weld material was solid....not sure what that molten material was but it wasn't part of the weld
While process take 90 minutes to complete
Great video thanks for uploading
Wow tajam bener gurinda nya❤❤❤
One thing is CERTAIN....if I, or ANY of my co-workers were caught wearing those SHOES that some of those MW&S workers were wearing, that is a basis for you being dismissed! This has to be outside of the United States! But the same basic principal.
Very good velding
Everything is very fine but the residual garbage includes polyethylene must be removed from site & sent at proper place.
If banane mai itna jhol jhal isko naksali kaise aasani se uudda deta hai koi unko bhi beje ye video sirf track na uddai aage ka soch kar ki jaan ka bhi haani hai unko bhi bhej de video 😢😢😢😢😢

Indian Railways is the largest employer in the world, I believe.
термитная сварка, использовалась ещё в 50-х годах точно... раньше не знаю, но возможно
У каждого своя технология сварки рельсов .
wow..sangat menabjubkan..
Мне нравится, как индусы умеют все ремонтировать и восстанавливать, у нас же в России, это будет просто замена всей стрелки...
Esta gente no sabe que existe un metedo mucho mas sensillo y eficaz - ALUMINOTERMIA!
Very good
No drip trays? Yikes
I wonder if the Railway company had closed the line off to trains whilst maintenence crews fix the broken rail. It's India, so maybe they have to do repairs inbetween train times on an open line which is highly dangerous to crews and railway passenger's. I hope it isn't the latter and that they adhere to common health and safety standards but judging on the attire of the work crew, I don't think they acoomodate much safety standards.
We know what to do
Lol so you really think we are that stupid, ofcourse train route are completely closed during maintanence time , they get 2-3 hour blank time slot to complete their work, this welding required 80-90 min for completion
Excellent
Сдается мне электросварка будет получче.
Ніт...не буде.
Такий складний (по-контуру рейки), бездефектний шов в польових умовах зробити неможливо.
...без єлектрошлакової заварки.
....декілька зварних з'єднань, зроблених за такою технологією (Харківська фірма спеціалізується на тому) довелось проконтролювати методами ультразвукової дефектоскопії...(згідно з Британським стандартом).
Ця технологія - робоча.
...десь так
Воде и камням не очень нравится воздействие высоких температур всё сплавить надо и шпалы тоже😊
Мда, это сборище каких-то фантастических долбоклюев, что много часов варили рельс, и сварили без температурного зазора, и шлифовали болгаркой по горячему... Хорошо, что у них там, видимо, один поезд в сутки проходит... Интересно, кстати, сколько та банка из нержавейки, в которой термит горел, выдержит таких надругательств? Два? Три?
線路のジョイントするところで、ミニ製鉄所ですか！？
凄いなー。
普通に溶接じゃダメなのかなー？
Amazing...🎉🎉🎉
I've been there/done that. But we all wearing proper safety gear also. LOLOL
Who needs OHSA 😂😂😂😂
Awesome!
The process is the same everywhere with continuous welded rail, but no PPE for the guys doing the work? Where is this? Somewhere with no safety culture.
Harekrishna18💚💚💚❤️❤️❤️❤️💚💚🤟🏻😂🙏🏻😊
Why we see the stones around the track ?
Слава Тебе Господи, что не придется мне и моим близким испытывать свою судьбу поездкой по железной дороге ни в индии, ни в пакистане!!!
В Германии тоже используют термитную сварку рельс 😊
Ahhh India……where safety is an afterthought. They also didn’t put the usual catchpans on either side to catch the extra slag/molten metal pouring out of the sides. Good thing they were on concrete ties, or else they would’ve set the damn track on fire!
Ага , то есть Водород в шве это пустяк. Ну и в целом процесс восстановления долгий и множество манипуляций без права на ошибку.
기계는 항상 위험한 도구 입니다, 조심하십시요^^
Please tell their supervisors to give them goggles at least for all of the sparks flying that is soooo dangerous to the eyes
That cost money.the railroad is using them like slaves?
That's some fine safety equipment, and I love how they're all wearing some sort of uniform just so you know they're professionals. Which third-world garbage heap is this? Mexico? 😂
I had never heard of this until watching a documentary entitled "Epic Train Journeys From Above" on TV last night in which this exact technique was used. Then this shows up in my recommendations today. Weird.
Походу, индусы))
Походу пакистанцы или малазийцы. Индия давно уже фору даёт.
nice
That's a very nice wok 🥘
No safety standards maintained there.
These are the exact same safety standards Project 2025 calls for.
Fortunately, they will never be implemented.

No flip flops? At least one has a safety vest on. Looks like one had gloves and steel toed shoes on.
Good Working please..
In this type of jobs, left-wing feminists do not demand job parity...
Вна Украину надо продать эту технологию. Стопудово зайдёт.
Ця технологія, в Україні, вже давно працює...
Алюмо-термітна заварка - річ вже давно відома, але німці зробили продукт...
...набір інгредієнтів і опок (одноразові форми для стиків рейок) + оснастка для послідовної подачі необхідних матеріалів в зону зварювання.
Саме така технологія іі використовується.
...єдино, що не побачив в цьому ролику - це зняття залишків з усіх профільних поверхонь рейки за допомогою спеціальної гідравлічної оснастки...
Головку рейки якось-там зрізали, а шийки рейки - так і залишили...
....некамільфо.
...я так думаю 🤔
Wauuuu. Mantap
