I would imagine, that there are bigger machines, which make the process a lot more comfortable and faster, but they maybe too expensive for just „some“ joints.
everything we do is about transferring energy so it would make sense that the tool made to transfer energy to pretty much anything is pretty essential lol.
Yep they know what they are doing. Its a old video and lots of things could be done "smarter" like the hammering afterwards. We did that years ago to get the excess stell off before grinding. Now you just lift the yellow cutting machine (what you see in the video after they welded it) and rip the steal off without damaging the weld. It saves lots of energy and time for everyone. Its a tough job but very well paid.
I Thermite Welded for the CNR back in 1981-82 (then Joint Welding and Magnesium Frogs). It was very similar to this video except for the crucible. Ours were much more antiquated ! But the Molds, Shields, Slag Pots and Packing Paste appear "almost" identical. We used Hot Cut and Sledge for knocking the over-welds off but eventually were rewarded and equipped with (what appear to be the very same) hand-powered Sheers and ultimately Powered Sheers.
When I was a little kid, I actually wondered... "How do they transport and install such massively long metal rails? It never occurred to my kid brain they were welded from smaller pieces. I thought rails must be installed from small pieces. But I never saw any seams so I ruled that out. So I thought to myself, "How the F do they do it?" HAHA! In my defense, not many 10-year-old kids have a concept for welding. C'mon.
Fantastic, I studied this process 50 years ago as a welding apprentice but never saw it before, this joining of railway lines was the only application it was used for then. For those that do not understand welding, it is still done today as before because while the set up is slower the overall process is faster than a manual process, the rail contour would be a pain to manually weld and dam. Thermite welding deposits a very high quality weld and not to forget this is a "Hatfield Steel" an 11 - 14% Manganese steel, not so easy, except of course to you experts out there.
Howard Glen Flashbutt welding is used in the manufacture of long lengths of welded rail, but when it comes to joining those lengths up in situ it's usually thermite welded
David Richards Not so, there is mobile rail flash butt welding machinery available, it doesn't tend to get used much because difficulties with track access, availability and cost all tend to favour aluminothermic welding currently.
David Richards Thanks David, you saved a non-welder (that would be me obviously) from asking what might have been a silly question. My first thought was stick weld it, apparently that would be completely wrong.
Thank you for your knowledgeable reply Simon. Many decades ago, when I was a teen, I spoke with a chemist who told me that decades earlier this method was used to weld trolley tracks.
There must be a lot of sprained ankles and knees in this job. Moving heavy, awkward equipment around between rails and ties it's just a matter of time.
@@ratatad4944 I'm making an educated guess so take it or don't. I'd say with the physical labor, skill and risk added up... bout 50 an hour with a very decent retirement plan. (The skill and risk are the factors the labor doesn't command a high wage) I'd wager the Obama care scam fucked these guys out of about 15-20k per year in medical depending on how many children they have.

@@richardpatterson4312 This video is in Sweden. They have universal healthcare (which obamacare was fundamentally trying to implement in the US) therefore rendering this comment about obamacare invalid.

I agree about the safety glasses comment and it does look like they will be in dire need of yoga to avoid health issues.
I commend you on going to med school--- and watching videos like this---, but I ask you to please study WHY western medicine does not cure disease, but only treats it. Be one of those rebel doctors who does not just write popular prescription, but actually tells people to eat right, exercise, take iodine, supplements, and things like colloidal silver and liver gallstone cleanses when needed...
since I read this comment and watched the video again it really shows a super human with flaming gorilla arms trying his chance in welding industry. I cannot stop laughing, thank you.
I thermit weld now for almost 4 years and i can tell those guys are experienced even tho you dont see how they prepared the rail for the actual welding process. Like cutting the necessary gap with a flame torch and setting the rails even with almost zero tolerance. Hats off to anyone who survived this job for more than 1 year. Even tho you see the "actual" work done its also the easiest thing about the day. But carrying this heavy equipment to where the rails have to be welded is the hardest part for us. Sometimes we push it on a wagon that fits on the rail tracks miles since u cant reach it with the working car & if you have a bad day you have to push it uphill. To this day its always a challenge, for all of us. Guys who looked like the rock quit after 1 week saying its too hard for them. This job exposes men that thought they are the toughest. Having and finding the will every single day is what keeps you welding rails no matter how tough you are. So if anyone looks for challenge i can recommend to go for it. The treat you will get is good money and back pain really fast x)
@@davidthedustyhampton690 iirc thermite gives off a lot of UV, so UV blocking glasses may be what the safety folks are asking for. Also if your thermite goes crazy you can get sparks and little bits of metal flying around, which they probably would help with, just not the molten stuff.
Cool video. One of those things I've never thought of it's how they weld track rails together. I just assumed some guy out there with a portable arc welder
Wolfgang Lendner even with more ballast in b/w there, those ties seem a lot larger then what i normally see here. is the track gauge any different too?
sik59rt The track gauge is mostly 1435 millimeters here in sweden, but we have a couple of active tracks (Roslagsbanan, for instance) with the older gauge of 891 millimeters. On Inlandsbanan shown here (which is not part of the regular railroad network) they mostly have tourists and residents travelling. I'm not sure what the max speed is because it differs due to location, but the trains can make it up to 130 km/h.
Isn't this before the ballast ? You have to surround ties whether concrete or wooden to prevent shifting I would think. Unless the concrete ties are so heavy they require no ballast, but I doubt that is the case. Interesting video.
Thank you so much for this tutorial. My buddy and I are trying to build a railroad track through are back yard and couldn’t figure it it how to do this part. We went through so many termites😂
Great video on thermite railway welding for tracks in Sweden...Europe seems to always be on the cutting edge with many manufacturing and transportation technologies..
I'm a Union Irinworker in Ct, and we rehabbed a railroad bridge in South Norwalk, gotta be almost 20 years now! I watched this up close and personal. It was pretty cool shit!
@@SgtStickyTits the welding itself isnt much labor. But preparing and moving heavy equipment is what is killing you. Trust me its tough and most men dont survive 2 weeks as rail welders
Loved this video! We watched it in science and I found it really entertaining, my teacher said it would be her dream job -bit weird- but thanks for the insight to this amazing profession.
Great respect to their job. Hardly to imagine what forces act at the welding points during summer and winter (push and pulling forces, hot sun and cold froze). The welding must last for a long time.
Yes, I worked with the aliens and the NSA putting thermite in to cause downfall of US America, thermite everywhere in building, lifts, carpets, sandwiches. How you discover?
Well only some of the gaps are welded there still needs to be some gaps left cause of thermal expansion so that the steel would have space to expand uninterrupted
First it doesn't cause stress on the train only the rails Secondly when tracks are bolted together a gap is still left between the tracks and the bolt holes are wider So that's how you avoid stress just leave some gaps once every few dozen meters of track
Israel Ayala Could you explain why? I like to see people working with impressive skills and using advanced technology. A tad better than seeing all those smartphone zombies staring at their screens with blank eyes while sleepwalking through red lights.
Welding rails together creates a rigid and smooth joint that is safer for bullet trains. (Unless they forget to grind off the slag - happens on a union job between shifts sometimes ;-) Ties are buried after welding because the rails can warp from heat cycling and require additional straightening.
The coolest part about the new way of building tracks is what the end of them look like. On the boston t, in the winter there's about a 1/4 mile, if not more of unused railroad ties at the end of the line, in the summer there's almost none left cause of the expansion of the tracks.
They're putting in a new rail beside my building right now. I was wondering after seeing the separate rails that all appear to be one long rail now, how they fused them so perfectly.. I came across this video randomly without searching so that was a nice coincidence. Anyway, very interesting!
Honestly, probably the fastest way to weld it in the field with a certain tolerance of quality. It takes 2 guys. It only take what looks like $25,000 of equipment, probably less than 2 hours of work from start to finish. There are many many many ways to do this with higher quality, but those ways would be slower, require more expertise, would be very hard to do in the field... Or if you managed to fix all those problems it would be fabulously expensive. But then again, there is ALWAYS a better way... ALWAYS... Its a question of cost of resources, time to complete, cost and time of the workers, ability of the workers, requirements of the job, what vehicles you already own... ect ect ect. TL:DR There is always a better way. For some reason, cost/time/ability, thermite welding is often chosen for railroad construction. Source: Welder certified in D1.1 6g 2in sch80 steel pipe, D1.1 steel plate groove unlimited thickness all position, D1.1 steel plate fillet unlimited thickness all possition, D1.2 aluminum AWS D1.2 (2015)
Which requires 16,000 more welds, or 32,000 if you count both sides. They weld just every 200 meter or so, which means a true professional team like this can cover many kilometers in a day's work.
The extremely specialized equipment (this ain't your body and fender spot welder) and the procedures that have become second nature to these rail workers is what is impressive to me. Curious what the dollar per hour wage would be for this type of work. Thanks Mr Lendner for the clip.
I will explain. 1) There is a clamp in place to hold the ends together as he heat treats them. This clamp also acts as a guide/holder for the thermite. 2) They use the thermite to bond the two ends together using the heat and pressure generated. 3) They remove the apparatus and clamps then proceed to knock off the slag (waste material) on the outside while it is still hot and brittle. 4) All that's left is for it to cool (which takes a while) then polish out any rough spots and check the quality of the weld. You can see a finished weld behind them if you look closely enough. Hope that clarifies things for you. :-)
I think the machine that laid down those tracks is just amazing and I would love to see it in action in person I really do. Thanks for sharing and for your hard work in keeping the rails open and safe!. 🙏🙏🍻
Watching this and seeing all the specialized tools and machines that have to be manufactured specifically to do a particular job, is just amazing. Never seen anything done like this before . I'm assuming it has definite advantages over conventional welding which is why they're doing it? Stronger weld?
When you mix fuel, metal oxide and metal powder in just the right way, it burns at two thousand degrees Celsius. Hot enough to cut through nearly any barrier known to man. Throw some C4 into the mix…and you’ve got one hell of a combination.
This is the appropriate amount of talking on the job.

Honestly, probably the fastest way to weld it in the field with a certain tolerance of quality.
It takes 2 guys. It only take what looks like $25,000 of equipment, probably less than 2 hours of work from start to finish.
There are many many many ways to do this with higher quality, but those ways would be slower, require more expertise, would be very hard to do in the field... Or if you managed to fix all those problems it would be fabulously expensive.
But then again, there is ALWAYS a better way... ALWAYS...
Its a question of cost of resources, time to complete, cost and time of the workers, ability of the workers, requirements of the job, what vehicles you already own... ect ect ect.
TL:DR There is always a better way. For some reason, cost/time/ability, thermite welding is often chosen for railroad construction.

It's cool to watch when everybody knows their job and works together without a lot of discussion or direction!
only 2,000 more miles to go.
Which requires 16,000 more welds, or 32,000 if you count both sides. They weld just every 200 meter or so, which means a true professional team like this can cover many kilometers in a day's work.
Not all rails are welded together tho
Easy money
😂😂😂 These are the real MVPs.
Lmao
What man on earth. would pick an office job over this?
a man who wants to live past 65 probably
My Dad is 70 years old and still busting this shit idk what your saying....
King Koopa 70 isnt really that old lmfao
Ook smarty pants im done here.. so what is live past 65? Idk i cant deal..
Anyone intelligent and wants to earn a top salary?
Great job fellas. Nicely done!
Those tracks are looking real sturdy and high quality 😆😄
Too bad we cant see an upclose view of the finish weld.
you are urinary.
demo2382 it's not finnish it's Swedish.
almost7891 you're dumb. he meant the finish weld, not Finnish, he means the weld after they are done with everything
@@Someone-cb3zx relaxxxxxx..😃..
@@lorditsprobingtime6668 OUCH !! ..🌟..👍
All that and not one shot of the nicely ground and cleaned weld afterwards ? Come on now you missed the best part !
It didn't look like they filled the weld. There's like 1 cm missing at the top.
You can see the end result from afar on the right, though.
The extremely specialized equipment (this ain't your body and fender spot welder) and the procedures that have become second nature to these rail workers is what is impressive to me. Curious what the dollar per hour wage would be for this type of work. Thanks Mr Lendner for the clip.
Fascinating thanks for sharing .Bloody hard work .
Why didnt you show the track after the finish?? what was being done? No one said a word?
I will explain.
1) There is a clamp in place to hold the ends together as he heat treats them. This clamp also acts as a guide/holder for the thermite.
2) They use the thermite to bond the two ends together using the heat and pressure generated.
3) They remove the apparatus and clamps then proceed to knock off the slag (waste material) on the outside while it is still hot and brittle.
4) All that's left is for it to cool (which takes a while) then polish out any rough spots and check the quality of the weld.
You can see a finished weld behind them if you look closely enough. Hope that clarifies things for you. :-)
Zeb Cheek thank you! Very kind!😉
Welcome
this is just wrong...a civilized conversation in youtube!!!
just kidding of course :)
-Thank You.
I didn't know that termites could do anything constructive, so good for them.
It's thermite, not termite.
LoL 😂
Perfect after the builder machine video. Thank you!
Thank you for uploading this video...
0:46 Cool sound
Excelente trabalho, e um grande preparo com ferramentas precisas
I think the machine that laid down those tracks is just amazing and I would love to see it in action in person I really do. Thanks for sharing and for your hard work in keeping the rails open and safe!. 🙏🙏🍻
Such a simple yet fascinating process.

Safety glasses in place! Firmly on top of the head! A well safe working environment! At least the other bloke had sense!
+moleman1961 I noticed the lack of the safety glasses also. I can't imagine doing that type of work without them.
Wow those guys are good! Some cool science making all that work. Gg
So much admire skill and teamwork!
Watching this and seeing all the specialized tools and machines that have to be manufactured specifically to do a particular job, is just amazing. Never seen anything done like this before . I'm assuming it has definite advantages over conventional welding which is why they're doing it? Stronger weld?
Speed
I wonder if the Concrete Ties they use are better than the Wooden Creosote ones we use here in the States?
You Railroad boys sure play with some pretty cool toys!
This is awesome I had no idea thermite could be used for this
I love that sound of cracked rail in 0:47
When you mix fuel, metal oxide and metal powder in just the right way, it burns at two thousand degrees Celsius. Hot enough to cut through nearly any barrier known to man. Throw some C4 into the mix…and you’ve got one hell of a combination.
M C thermite= big dumb
Nobody knows that for sure
Rust and aluminum are very uncommon materials in modern construction. Pretty fishy if you find them. right?
Jet fuel seems able to cut through twin towers
Is this a 911 reference?
Great. Now I am addicted to watching rail welding videos.
Hard, dangerous work! That is a real job.
Here I am again, visiting this fabulous video and to hear that twang at 0:45
REAL MEN DOING REAL WORK! GOD BLESS THEM.
I love how they use a regular fireworks sparkler as a magnesium fuse. :D
i do this at least 4 times everyday its awesome!!
That is a lot of work for welding a few rails together. Seems like they could do it easier with an induction coil.
But that would require a somewhat beefy power source and it would probably still take longer to weld than with thermite.
Barnacules Nerdgasm it will be much easier to use Superglue
