Rails welding by aluminothermic process on the Serbian Railways. The video shows three weldings and the complete process of welding work.
The most interesting sequences are eruptions of burning thermit, squeezing of glowing, liquid metal and finishing rail grinding.
The complete process includes:
- Leveling of rails to be welded;
- Preparing the mold;
- Sticking mold cavities;
- Preparing fireplaces (fire and eruption caldron);
- Thermite eruptions;
- Liquid ironing;
- Squeezing melted iron and molds;
- Breaking surplus materials of iron and molds;
- Rails grinding and
- Finishing work process, preparing rails and tracks for test drive...
Recording locations:
- Railway station Rakovica;
- Kosutnjak, Belgrade
Date of capturing: September 2017.
Memories , way back 1995 to 1999 . I used to do the same job . And my cousin Bro Gilbert is in flashbutt welding team. We are running 6 thermit team welding day and night . Exactly the same method . The crucible / thimble , silica sand molds , the hydraulic shearing and grinding machine with small motorized trollies too. Thanks for your video , you just brought me back once again to my old adventure. Hoping my old mates watching your video too . Aris Idin , Damo Daran Antonio Crispin , Domingo Cocal , Ireneo Evangelita , Rex Hababag and many more .
This is an example of the best that can be done in a video showing "how it is done". So many of them lack detail, so that the actual process is still a mystery at their end. Best, by far, of the dozens I have watched. This shows all kinds of wonderful details, not shown, and sorely missed, in the others. Dulevoz obviously had complete cooperation of the work crews. Not only that, but Dulevoz, includes the location, which is essential to many of the videos I watch, but is often missing.
I'm glad you noticed this. It would be great if every video had at least a bit of essential information, such as date and location. Unfortunately, this is not the case.
and no stupid music...
Tom Oakhill the thermite welding I have inspected (I was an NDE technician and AWS CWI not regularly inspecting rail welds) I made sure the rails were spaced proper then the guys would use a form, touch off the thermite then use a a hand grinders to grind down the rail.. After that I checked it visually, them Magnetic MT for surface indications then I used Ultrasound UT Shear-wave for internal indications, if there was any indications depending on how big and what we determine they are, porosity, lack of fusion or actual crack, the chunk of slag under the track would send you a great big indication on you UT scope every time and with varying intensity and size... it will make you want Offshore MODU surveys or a fab shop fast
Why not use one of these..... kzhead.info/sun/abJ_j7qxmpaqeIU/bejne.html

I HAVE WITNESSED PERSONALLY THE SAME EVENT IN MY HOMETOWN WHEN I WAS 9 YEARS OLD THEY WELDED RAILTRACKS, NOW I AM 54 YEARS OLD AND THIS IS THE SECOND TIME I SAW THIS BUT NOW IN YOU TUBE. THE WORKERS MADE IT 100% WITH HEART AND SWEAT, JUST TO MAKE SURE A SMOOTH AND SAFE TRAVEL OF TRAINS PASSED ON THEIR WELDED JOINTS
this goes to prove that no matter how much education you pursue, if you cannot apply anything learned and figure out solutions in everyday life, your knowledge is useless. I learned exothermic reactions on paper in chemistry classes. Certain oxide compounds mix and create heat. Reduction, Oxidation laws etc. But if the ministry of transport approached me and asked for a viable welding solution requiring oxidation of metals, i would probably never be able to come up with something so simple as this. Thermite was invented by an American railroad engineer. Just some simple know-how of high school chemistry, and viola - you've revolutionized welding.
Thank you for your attention to detail and patience with the camera. This is a seriously underappreciated video. I do not understand why 2k people would down vote this. For the topic this video covers, it is excellent. If people don't want to watch tracks being welded they should go elsewhere.

When i worked for Amtrac railroad years ago i did this job welder. I absolutely loved my job i stayed welding rail for several year's. When i got a promotion i went from welding to transporting the heavy equipment like the regulator's and various other oddities that are used to build and dress and or set the rail's. Thankyou for sharing this video i can now share it to my friends so they can see what i have talked about so many years. I had a-frame jacks to set my track up for welding i used an old method that my mentor taught me he used a nickel to judge the rise of the raiks so that when they cooled the rail would be level l ik ke i said really cool job that has left msny great memories Takecare and keep safe
What’s this nickel trick you are talking about?
We still use the nickel method to measure the “crown “needed at the rail ends ,usually with a 3ft straight edge….although now they have adjustable straight edges where we can lock in the height at opposite ends….
these are the people who ensure a smooth ride on a train. Great men!
I love the way the thermite burns up and flows into the crack...its like lava flowing...I could watch this all day and still not get bored...those guys look like they could weld tracks even with blindfolds on.
Hats off Great men Great workers "Dignity of Work"
And always wear safety goggles, they are cheap, eyes are not.
Goldschmidt aluminothermic process :) read it first time 12 years ago
@@cintulator2 but they wear helmets, for a reason not known by me.
@@cintulator2 who cares about hats & glasses ffs
Not to take for granted that beneath every smooth ride, is laid with many tons of hard work and dedications..
Manual labor, the only real job for a real man. A man that cannot handle a sledgehammer is a sissy...
Words fail me to describe the welding!!!
What do you know! Sunday evening, I have diarrhea and this is probably the most interesting vid I've seen all day!
Fuck man, what are the odds? It's sunday morning here, i have diarrhea, and this is one of the most interesting video

CT il bu ti seguo siamo
This appeared on my recommended, I watched and I'm not an engineer, I'm not a railroad worker nor a blacksmith, I just found it really relaxing and interesting.
Hope you recovered from the shits,man.
First class track-work there guys. Great job.
Mm
Goggles would be great too, they are cheap, eyes are not.
I've never searched anything to do with either welding or trains. But here I am watching this.
When I was on Pway back in 80s, we used to pump the Hydraulic Cutter by hand, then tidy the Weld with an Angle Grinder. Good part was , the 2 chunks of excess weld would be tipped out onto the Ballast and used to make a Brew. Surprising how long they would stay hot, I know, I stood on one Lol.. Another job was, rebuilding Crossing Noses . Build it up with Welding Rods, Grind down and Reshape Nose. Mainly on Diamond Crossings.
@@TheFalseShepphard "it was hard work " but, "the cup of tea after made it worthwhile " lol. Was nowhere near as much mechanized Stuff back in the eighties. Made some good memories though. Thanks for sharing. 👍
We really LOVE that GEISMAR Weld Shear. Although more expensive than the aluminum one, does a better job even with larger or crane rails. And the MP-12 grinder is legendary!!!
Seems like these guy have been working on the railroad all the live long day.
So Dyna can blow her horn.
@Mike Oxmall... and yet here you are watching railroad related videos???
@Mike Oxmall You better quit watching these things then and take care of that brain of yours Lol

Love this style of video straight facts, excellent on site video work and no annoying music, just the facts. I also enjoy seeing these eastern European countries showing what they are capable of and getting stuck in for their country, inspiring.
To all dedicated rail road workers, May God Blessed and Keep you all safe and in good health. Thank you for your hardwork.
Amazing really what goes into joining a track. Great quality video too. Enjoyed that. 😊👌
Thanks for posting this. I really enjoyed seeing how this is done. Fun to watch!
You're welcome.
Iam a track maintainer in Indian Railway, I know this is very hard work 👍
Hey thanks for posting this video. Also for taking the time to subtitle the process.
On my train set, I just pushed the small metal pieces together, and bit off the plastic ends...still the same work to this day.... seems legit....
Right On Bro. Me Too
hahahahaahahahaha
Damn those employees were so professional. Hats off. Everyone know what they were doing. Best part is when person leave and stand aside as soon as his work finished. Great
Routine
What an interesting Video!
snimak je kristalno jasan ..svaka cast
Très intéressant, beau travail.
That was interesting. Thanks for posting.
You're welcome.
Great video, but I'm amazed at how many workers are not wearing safety glasses.
Thank you for your work.
Show o trabalho, muito bonito, parabéns à todos!!!!
Excellent work done greetings from Greece❤️

Thanks.
Very interesting. Thank you!
You're welcome.
Great work! Congratulations from Brasil.

Good job guys keeping the track's safe
Excellent job... well done!!!
Good to see how its done. Stand well clear!
but not back to the traffic.....squish.
...and don't stand down wind!
@@scottleft3672 Do these guys even have a lookout man ???
@@ianjones4116 They use an ACTUAL cockatoo.
Very good job that is the best joint i ever have thought , i walk thru the traks watching the gapes and i could see the disaligment they have to each other and it makes alot of noise every time the train pass on . so that is the best solution thanks .
The gapes are there because of en.wikipedia.org/wiki/Thermal_expansion
Oh, how I wish I could know why I like watching a video like this !
Nice :-) Thankyou!
I was always wondering how they remove the extra stuff without grinding the rail for many hours but the hydraulic thing makes sense.
In germany the Hydraulik Thing is much smaller and more easy to lift. But its still heavy ^^
@@herrwaldrabe90 in austria you have to pump it. Exhausting ....
Very interesting - Learned something new today about rail welding! - Thank you
Very Intresting&how they Could Joint Rly Pattalu.of Track.
That was actually quite interesting. Well done.
Thank you! You taught me well!
Eu não sei porque estou a ver isso na minha cidade nem trem tem , mas estou adorando ver estes profissionais trabalhando com tanta dedicação;greetings from Latin America Brazil, Monte Alto state of São Paulo
I always wondered how they replaced / fixed railroad tracks. I didn't expect it to be so labor-intensive though. Great video!
P
Actually goes pretty fast considering attaching a HEAVY piece of steel, at both ends, that carries a TREMENDOUS amount of weight. I used to watch this process on the railroad tracks that ran through the back yard of my old house. The guys were very quick, and efficient at what they do.
This may be a slow way of joining tracks, but IMO, it most certainly is the best way, as those tracks are staying exactly where they where laid... This and the fact that it should be the smoothest train ride you've ever had, and you probably won't get the clickity, clackity of the the railway track. Thumbs up to these rail workers and the work they are doing 👍👍👍
... good to see advanced techniques in operation
Congrat guys. But couldn't it be done with less material at the beginning. Just asking.
This was totally fascinating. Thank you!
Thanks for a very good video and info!
Very informative; thank you!
Everything is heavy, sharp, and one million degrees.
Tough, hard men.
Always wanted to see that being done :)
These guys are all older than dirt..., OLDER and WISER. It takes a long time to get that good. Nice work guys.
I got to watch a crew do a repair with the thermite at the Amtrak station in Portage, WI years ago. It was pretty cool.
Nice work fellas! While an outsider passing by may think "a bunch of guys standing around" what is really happening is a well oiled and finely tuned machine at work. Very efficient, everyone knows what they need to do and when to do it without need for verbal commands or instructions.
Not exactly... Here in Serbia it is common to see more people standing and watching those few who work. Especially in state owned companies. Relic if the recent past...
It's that way in many countries of the world.
Sehr beeindruckend! Danke!
Bitte.
the Best Job rail way connecting welding... BRAVO Team Work...
I am amazed! Completely captivated by the technology!!!
at about 8:22 at the top left you can see the last remainding V3000 (ML2200) engines of Titos "Blue Train" (see en.wikipedia.org/wiki/Krauss-Maffei_ML_2200_C'C')
7:06 - I see work crews are the same all over the world, one or two guys working and everybody else standing around watching.
there is another video just like this one in Sweden, but it only took 2 workers, not 6, to do the same job, interesting..
@@eduardodelrio2914 Yeah the German one has 2 workers also.
That is exactly what I see when I go to work. Everybody has a job but only 2 people actually do the labor work
2 guys work for the welds. The other ones standing around are hired by another company. They lift the rails how the welders say. They heat the rails to extend the length and make it weldable perfectly. Its not that they stand and do nothing. They just have to wait for the welder to finish
Well, as a partial defense (for this and others like it) learning to do some jobs is not as simple as our current educational system will lead you to believe. Many jobs don't follow the idea of School Education > Skill. In this case, I would not AT ALL be surprised to find that any of these guys were apprentices/masters. Sometimes, you stand by and watch something a dozen (or more times) before it is your turn to "give it a go". You are expected to be observing things and learning while you do the "shit work" like holding an umbrella, dragging the supplies from one place to the next, or staying there while it cools "and come get me if anything catches fire or makes any loud noise". Also, it is pretty clear that not all of those guys are part of the welding crew. Most of them seem to be on-site to do something else. Those guys were probably watching the most interesting parts (Which is pretty much ALL we see since that is how video gets edited).
It looks like a very easy job. A lot of moments of pause and watching fireworks.
I felt like I just got on the job training, this is amazing.
So now I don't get to listen to the "clickety-clack " as the wheels rolled over the old open joints! Those were peaceful sounds.
And now the rails buckle if it's a particularly hot day
Good job with what they have. Early 1900's way of doing this.
This process is in use all over the world. Nothing old about it.
*Excelente trabajo y buen video Saludos desde México*
Всегда интересно смотреть разные технологии изготовления всего что нас окружает. А кому не интересно,то зачем смотреть,а потом дизлайки нажимать,а сам то диванный специалист...
That looks like a fun job, lots of sparks flying and molten iron running....what is not to like about that? The process is well covered and explained...good job.
Thanks.
My friend did this for a living and said dropping a vat of active thermite into a depp river is good for a show.
It is lol
@@g00niez LOL , indeed it makes steam rapidly with a resulting explosion and hot flying debris!
@@rogerpoke4919 oh yeah
I’ve done thermite welding and it’s amazing the heat produced from a basically a powder that is ignited to melt the rail together
Video bello, e molto interessante vedere questi lavori ferroviari!
This is just like casting iron!
We did this thermite reaction experiment in the chemistry lab at grammar school in the 1960s and used a magnesium ribbon fuse to ignite it. I can't imagine they dare do it these days.
In my grade 12 (senior) highschool year, only maybe 6 years ago or so, I had a "spare" half day with no classes one semester, and occasionally volunteered to peer tutor the younger chemistry class, run by my favorite teacher, famous for her "energetic" demos such as blowing up balloons filled with oxy-acetlyne mix and so on. Presumably, she correctly deduced that my real reason for my sticking around to help the students balance redox equations and whatnot, instead of just getting high with my friends, was that the most attractive half-dozen girls in the school happened to be in that class😂 anyways, she let me pick a reaction to demonstrate and explain to the class every Friday, which was seen as a reprieve day from the normal class paper work stuff, so I came to be well-liked by them... Once I blew up about a pound of thermite after downplaying it as a boring thing. I believe I have that footage somewhere... teachers came from the adjacent rooms to see what all the screaming was about. Good times ahahaha
For mange om et simpelt arbejde 🤯🇩🇰
I Danmark er der ju en 2 man hold grænse 😂
Браво мајсторе!
This same process is used in the U.K. as well,very interesting to see it up close. Skilled Men.
Sorry mate most are not skilled welders. Easy work.It used to be good money,better than real welders in a lot of cases
We use one shot pot in the uk now and have done for a number of years... This weld would have failed, the moulds were over cooked, nothing was timed the adjacent line was open to traffic and could have dislodged the weld. So many things wrong here .........,
Allan Mcewan most welder are pensioners and still working because of low income and younger workers are working outside Serbia. not just welders all branches when gets pension they back to serbia to live
milos gocic It is not a good trade any more,if it ever was.
Fascinating video. Like the attention to detail in filming.
Thank you.
Gromitdog1 く
It's always a mind-blower to me when you see ANY crew working on train tracks......75 guys standing around, 2 or 3 working (moving at least...)
Great video !
I am most impressed by the ram seals withstanding the heat. They're some cool seals. Pun intended.
Do you mean the hydraulic rail tensioner? I don't think a "ram seal" is a thing
@@Starkl3t Of course a hydraulic ram has seals in it. How else would it make or hold pressure without seals? Gosh matey boy you got some learning to do before you try and correct me. If you don't understand my post move along or do some research don't try and correct me like I don't know what I am talking about and you are a genius, ffs KZhead expert. Why not try and be helpful to others instead of trying to 1 up everyone and end up looking silly.

It's not the safest way of doing this, in Austria we use One-Use thermite cans instead of that steel funnel. These are closed on the upper side so that it doesn't erupt like that - these eruptions can be pretty dangerous, especially on hot summer days when welding near a forrest or grassland. Other than that, the process here in austria is exactly the same.
I agree that this is a dangerous way of rails welding. Serbian railways will have to change the way of welding, once.
ShazenVideos some rail grades do not have single use crucible available so this could be why the reusable crucible is being used.
That eruption bleeds off excess energy... Like all UK engineering since 1950's is like teaching retards.... That funnel bleeds off tons of toxic fumes in the process while the product is working... Like our country they design the most useless process and shit to get away cheap and stupid at the workers health expense...
And just a few of these guys had the brains to wear any protection. I could only see one person covering up his arms and wearing gloves. Maybe he was the one learning the lesson the hard way.
Shazen Russia?
Done that welding for thirty years with Irish Rail. Slightly different system but same procedure. Difference been the moulds were not as big and the steel was poured from the side, using a pouring cup . We only used these moulds in gantry rails at docks . Interesting work but heavy work as all the gear was heavy. You welded so much lengths together and you had to stress it then remove the expansion. But that's another story.👏
Very,very good work! Congratulations and greetings form Como, Italy
0:19 In the background there are at least two of the three ML 2200 (respectively D66 at the JZ) visible, which used to be in service for the former Yugoslavian governmental special train of Tito: en.wikipedia.org/wiki/Krauss-Maffei_ML_2200_C%27C%27 What a pityful view...
So trains don't go claky Clark any more.?
Beautiful video with experience job
Amazing work
Bravo for the workers!! Good job bro.
Thanks.
Thanks to those anonymous heroes, the great train workers!
I can watch this all day

À great technology where I observed the application on over head cranes track rails in a steel plant a good old organisation bhadravathi .100 years company is efforts of great maharaja of Mysore and sir M visweswaraya during 19th century.
Rough day? Well watch these guys melt some metal and join some rails together, chill you right out it will.
excellent video for thermit welding,I saw from Bangladesh. thank you all
This is very interesting. I'v seen spray welding but this is pretty cool!
