HTML-код
- Опубликовано: 27 сен 2024
- 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 .
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….
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.
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.
Hats off
Great men
Great workers

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 👍👍👍
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.
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.👏
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...
What an interesting Video!
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.
the Best Job rail way connecting welding...
BRAVO Team Work...
Hey thanks for posting this video. Also for taking the time to subtitle the process.
Words fail me to describe the welding!!!
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

Best comment on RUclips
Oh, how I wish I could know why I like watching a video like 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. 👍
I am amazed! Completely captivated by the technology!!!
Very,very good work! Congratulations and greetings form Como, Italy
I've never searched anything to do with either welding or trains. But here I am watching this.
Excellent work done greetings from Greece❤️
To all dedicated rail road workers, May God Blessed and Keep you all safe and in good health.
Thank you for your hardwork.
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.
These guys are all older than dirt..., OLDER and WISER. It takes a long time to get that good. Nice work guys.
First class track-work there guys. Great job.
Mm
Goggles would be great too, they are cheap, eyes are not.
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
Great work!
Congratulations from Brasil.
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...
Amazing really what goes into joining a track. Great quality video too. Enjoyed that. 😊👌
Great video, but I'm amazed at how many workers are not wearing safety glasses.
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
excellent video for thermit welding,I saw from Bangladesh. thank you all
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.
It looks like a very easy job. A lot of moments of pause and watching fireworks.
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
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).
Thanks for a very good video and info!
9:23 The rock is a good example of what it works whitout thinking to much.Good work!
Thanks for making this effort of filming the whole process of welding rails. I would like to thank for and you did a fantastic job in filing this amazing experience.
It's first time for me to see the thermite welding method .40 years have passed
after reading it. The study without experiences is difficult to understand.
Thanks for your posting. 🍀🍀
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
Iam a track maintainer in Indian Railway, I know this is very hard work 👍
That was interesting. Thanks for posting.
You're welcome.
Браво Дуле. Баш сам се обрадовао кад сам чуо српски језик а и кад сам видео да је у питању наша железница.
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 RUclips expert. Why not try and be helpful to others instead of trying to 1 up everyone and end up looking silly.

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.
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.
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...)
Sehr beeindruckend! Danke!
Bitte.
Me: home resting
YT: You wanna watch these dudes use thermite to weld railroad tracks, bud? Only 26 minutes…
Me: “YES YES YES!!” 🔥🔥🔥🍻🥇
Très intéressant, beau travail.
Uauuu, Sie sehr profi sind Leute!
Kompliment... par minuten und fertig ist. Prima, Danke ;-) Jiri
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 ....
Amazing, good projeck...
Fascinating video. Like the attention to detail in filming.
Thank you.

All that tech & machines & it still comes down to raw man power. Some things will never change
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
I can watch this all day
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')
Very nice weldone hardworking Rilway team.....
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
Thank you for your work.
In the uk the first thermite welding would have closed the rail network for a week and even if the work was done in Newcastle southern rail would have used it as the reason why their trains were cancelled.
Very interesting. Thank you!
You're welcome.
Surprisingly watchable, wouldn't mind having a go myself
nice job. only 1 900 000 000 000 000 more gaps to go!
Fidor had his daughter and wife with him on Thursday so only 1 899 999 999 999 992 to go
yup more money to make
BRAVO MAJSTORI ! Tome se kaže"stara škola"...
Rough day? Well watch these guys melt some metal and join some rails together, chill you right out it will.
my dad told me about the old timers that used to weld the track. what an craft job
Everything is heavy, sharp, and one million degrees.
Tough, hard men.
I felt like I just got on the job training, this is amazing.
Dude at 10 min wearing his helmet backwards, what a lad.
He's the cool guy
Ab so lute unit
Its like a giant cadweld. I have done this thousands of times for grounding systems, but on a much smaller scale.
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.
i like this very much, i cut a similar video a few weeks ago. BRAVO to your version
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..... ruclips.net/video/6NF_VycdtEM/видео.html
@@schmingusss those are expensive
It is a long time since I have enjoyed a RUclips video as much as this.
One guys job is to hold the sun umbrella. They must have a strong union.
Not so much sun as rain,even just one drop. Have you ever poured molten metal into a humid mold ? This is the reason of preheating with the torch.
I had a friend who worked for the local highway department and when he retired, his buddies made him a full-size official orange diamond sign that said "MEN LEANING ON SHOVELS." Awesome.

🙏🏆🏆🏆🙏
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.
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.

I see you got your priorities set well then.

Just the same as in the UK. But where are the safety glasses. Good welding

I don't get this video. The same clips are used throughout. It could be 15 mins shorter.
Lmfao, sparks flying everywhere, everyone just hanging around, no eye/ear protection...
Yes lots of deaf Serbian railroad workers that got sparks in their ears.
Dustin Eward it’s just a good idea. If you do any sort of industrial work you will know it’s just common sense to wear eye and ear protection. It’s just not worth the chance to lose your sight when there are so many things that can go wrong. Lots of guys here were wearing the right PPE and of course it won’t make em invincible but overall it makes a huge difference.
thats cos they know what they're doing and not just an onlooker
they're Russians. Check out the Garage54 youtube channel for more Russian fun.
Seems like a little game they play, lighting the termite , before it's over the target.
I’m siting in the toilet watching old guys welding a railroad. Wtf am I doing with my life!!??
I wonder how many people have the ritual of always watching RUclips on the toilet. It just makes you spend more time in the bathroom than necessary. Weird huh?

Congrat guys. But couldn't it be done with less material at the beginning. Just asking.
I would be nervous as hell working with these guys. They got thermite explosions happing 4 feet from gas tanks, other boxes of thermite and torch gas lines. Then some dude be grinding the tracks throwing hot sparks at a box of thermite
