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.

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. .
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 🤔🤔
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? 😂
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 !
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 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.
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.
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.
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.

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.
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?
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!
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.
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
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.
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.

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

It is not primitive, in USA and some European countries this method is still in use.

I had fun with Thermite welding in the 60s.

It was used on Sept. 11, 2001.

The last one I watched of this crew, they were sledgehammering of a piece of slag and cracked the weld right in two.

This is must from India because there are not wearing hand gloves and safety shoes 😂😂😂😂😂😂😂
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.
Great work 🎉
It's always great. We liked and enjoyed to the end. Thanks
wow, very manually intensive
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
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!

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

Running sneakers during rail welding????
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.
Why we see the stones around the track ?
