- This video shows you how to properly thermite weld railroad track. The thermite welding process is used to join weldments with large cross sections quickly. This weld was done in under 15 minutes. Thanks for watching and subscribing to TVWeld.

The base risers were knocked off way too early. They're only supposed to be bent out slightly so you can rough grind the top surface, field and gauge faces of the weld.
When bending the risers out, you need to be careful you don't create a hot tear in the top of the base.
Great video. Thank you
Really appreciate that everything is presented in a lesson followed by experience format. Thank you
I'm fascinated by all the differences in how this is done.
Great job you made it very easy
Nice video, watching from Nz. I noticed you guys cut the risers straight away. We normally let it cool for about 45mins, it’s easier to break off that way
Nice video I’m a thirmit welder and we do things a bit different but nice to see different processes 👍
Thermite welders can find work as dentists on the side.
Excellent presentation!
Great content. Thanks for the video.
What are the chunks of steel or slag left on the side of the rail after grinding? Othe videos I've watched used a grinding machine for this job that sits on top of the rail.
Horns, pretty much nothing, fir overflow slag channel
Great tutorial. Thanks
0:15 - Uhm... an exothermic reaction has nothing to do with "happen[ing] outside of the weld area." It's a chemical reaction that generates additional heat as it proceeds.
Subscribed sir. Thanks for the explanation
Didn't know stanley built tools like that!!
i was suprised to see that too not your usual DIY tools .
Great video
Dam, that's a lotta work. Had no idea... Good job guys, thanks for sharing.
Thank you for the this presentation.
Good video
Nice video! Thanks dood!😁
cool vid was interesting
I'd like to understand how come that slag moves to (those pans at) the sides that easily
I've see several videos of this and none of them explain the plug they put in the mold just before they put the thermite container on and light it.
Also a tube,they left the real parts out,and that so called finished weld looked like shit.would have failed inspection on FRA class #1 Track!
Leland Rogers this video explains the plug at about 3:30

You could get 10k comments if your buddy would have said that Stanley shear was throw away too as part of the kit! I watch one of these with a fancy track mount grinder. I thought that Green genset was the track grinder and like to fell over thinking Ryobi was making custom grinders for RR tracks! lol
The NS does things slightly different. I would say something about those bolt holes but ...
If you would than you only worked new construction. In the real world we bolt the strings together so the rails can still be used to move people. It can have 2 bolt holes actually. I do these welds daily and it always has 2 holes in passenger rail and joint bars that we replace with bubble bars until it’s tested.
In Hawaii they just use lava.
If you like this you should see our flash butt welders on the gangs. Its a riot.
Thanks very much for this video. That grind could of been better eh lolol
Any body knows the model of the stanley cutter?
where do you buy welding thermite?
The railroad guys told me they order it in some kind of kit.
@@TVWeld i am interested in doing some of my own welding experiments and home made thermite would produce raw molten iron which is likely terrible for structural welds.
the welding thermite contains additives and such, i have no idea what these additives would be but i assume they are various fluxes and manganese, carbon etc to alloy with the steel.
i've looked around a bit on google and can't find any suppliers for this specific welding thermite sadly
How many a day? Hell, I worked railgangs making 16 + a day, back up guys and learn how to weld, how many did you drop by the way, the vid doesn't show the lining the rail, packing the molds. Hmmm. What's the crown tolerance and the inside of the ball tolerance for alignment.
Lol uhuh.
16 inferior joints also.
I seen this before but not as detailed.
There is alot of work done before hand just to get it ready to weld.An that is VERY SHITTY GRINDING ,It wouldn't fly with North Folk Southern, When did they start having 3 men crews?
Thermit welding actually!
protection....
Great video! BUT Ooooohhhh Wackin on hot slag with No safety glasses!! Eeeeek! 12:03
It's ok, they hire men.
01:35 whats it look like BEFORRRE this things on😫
没凉就强行锤断了
shitty grinding job by them tho....
Yeah, exactly what I thought.
@@SuperLittleTyke damn 1 year ago lol
Precision not required. As long as the train wheels can roll smoothly over it...
@@timfischer It looked like shoddy workmanship. Other repairers do a nice clean job. Just watch other TH-cam videos to see how it's done.
@@timfischer surface is one of the most important part of railroad. I work for class 1. People don't want that. Causes more impact hence flat spots on wheels or and lead to pounding on track causing rail breaks ect ect....
Please edit for length. Real-time viewing is not required.
Thanks
At least I can spell.
Life is in real time.
If only the video viewer had handy controls for advancing and rewinding content.
You know how to weld but dont know the meaning of mold and mould. Lol
Good video
The NS does things slightly different. I would say something about those bolt holes but ...
yup my railroad would look at this as an audit failure start to finish with both welds failing and cutouts, and an investigation to follow. was interesting to watch though.
