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
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
Meio primitivo,aqui no Brasil quem faz tu isso é uma máquina moderna.Mas o tralho tá bem feito,beatiful!🇧🇷🇧🇷🇧🇷🇧🇷

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.
Put on Again met some Indian guys for few few beers lately twice. 😊 Enjoyed tr Company. From Ireland
Stumbled across this. Absolutely captivating.
This Technique
Is Marvelous!
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 😊🛤️🛤️🚆
Absolutely intriguing! It's unexpectedly captivating, isn't it?
Excellent result.
Thanks for the upload.
Great to see professional repairers in the field.
and their safety footwear !
'professional repairers'
😂
Beautiful job
@@johnster1964 ....in some areas, your comment is interpreted differently.😉
@@PANZERFAUST90 ....I think you "understood" the comment.😁
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.

itu bantalan rel kudu ada di bawah pas sambungan untuk memperkuat tekanan di atasnya,,,,gitu lho.....😊
Thank you for uploading the video.
Boa noite! Inscrita no Canal!! Belo flagrante!!👏👏🚂🙋♀️
same color temperature seen on the sparks on the side of the TWC before they collapsed
The last one I watched of this crew, they were sledgehammering of a piece of slag and cracked the weld right in two.
fingers and hands are versatile tools😌
Great job!!!!! they must be proud people!!!!🤫🔴🫢

Esta gente no sabe que existe un metedo mucho mas sensillo y eficaz - ALUMINOTERMIA!
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.
AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! tx for sharing!!! :D
Ndokubasa!! From earthworks, sleepers installation, ballasting and rail alignment.

Great great work
At least these guys aren't wearing pajamas and their night shirts. They have lower safety standards if any in the far east. Watched a BNSF crew of two do 3 welds and they explained their work which was nice of them.
У каждого своя технология сварки рельсов .
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 😢😢😢😢😢
Just imagine what "elf n safety" on Network Rail would say! lol
thermite is serious stuff.
white hot !
It's always great. We liked and enjoyed to the end. Thanks
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.
The same stuff they used on 9-11...... imagine that.
Мне нравится, как индусы умеют все ремонтировать и восстанавливать, у нас же в России, это будет просто замена всей стрелки...
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 😊
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, ...
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.
Ага , то есть Водород в шве это пустяк. Ну и в целом процесс восстановления долгий и множество манипуляций без права на ошибку.
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 🤔🤔
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
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.
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!
Very good jobs
is the method used worldwide? the question may be foolish question thou. i believe that no railway maintenance companies allow a worker to take video of their knowhow. im just wondering if the terminate welding method is shared around the world such that a bicycle shop clerk always dips a tire tube in a water bucket to find a hole of punk.
This vedio is from India !!
There's a guy with brand new white snickers!
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
That's a very nice wok 🥘
E bem atrasado esse lugar a tecnologia a inda não chegou air

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.
Those guys are fast.
Very good velding
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?
Excellent
Who needs OHSA 😂😂😂😂
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!
Походу, индусы))
Походу пакистанцы или малазийцы. Индия давно уже фору даёт.
Looks fascinating, but that's a lot of unnecessary effort. Couldn't tracks just be, I don't know, screwed together, so they don't have to always be cut and molded, when replaced?
Wauuuu. Mantap
wow..sangat menabjubkan..
😢 é muito trabalho pra emendar um trio no Brasil é mais fácil kkk
기계는 항상 위험한 도구 입니다, 조심하십시요^^
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"
Very good
Good Working please..
I see they're all wearing safety sneakers.
From Indonesia watch
Always use safety shoes when do this repairing works.

Indian Railways is the largest employer in the world, I believe.
Вна Украину надо продать эту технологию. Стопудово зайдёт.
ممتازجيد😮😮😮
there must be an easier way
PLUS SIMPLE POUR LE REMPLACEMENT D' UN COUPON DE RAIL NON COUPE PLUS SOUDURE ALUMINOTHERMIQUE
А где тот самый дядька в солнечных очках и загнутым электродом?)
Nice
This method was already used 20 years ago.
nice
Pilosopi bajapun putus waduh Geri
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?
Muito trabalho para poça coisa
А не проще целый рельс заменить. У нас пригоняют ремонтный поезд и меняют целый пролет в сборе и соседние за одно. Старый в ремонт.
У них стыков нет совсем, это специальный теплорасширяющийся сплав для компенсации колебаний температуры.
vous ne changer que la partie de rail concerner. a la fin vous aurez toujours de soudures aluminothermique a faire POUR UN COUPON DE RAIL OU POUR UNE BARRE ,je suis du métier.
@@alexnc2747 pas de joint oui a la place soudure aluminothermique.
@@alexnc2747 И нафига такие сложности?

Excellent video ! 👍
AWESOME AMERICAN ENGINEERING

Would it be better to change the entire rail, instead of this doubtful "surgery" repairing of its piese?
Interesting. But no PPE.
Not required when appling common sense.
Definitely not in the UK with those soft shoes

What on earth is happening?
A crew on an Indian railway are fixing a broken rail. I thought it was pretty evident 🫤
@@acidz0037 I was talking about the specifics, not the general action of fixing a railway itself.
@@chad5893 There is a long comment from a couple of days ago that explains all of the steps.
Safty first 😂
