Thermite Welding

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.

Really appreciate that everything is presented in a lesson followed by experience format. Thank you

That's awesome 4 to 6 welds a day!! Far out in aus we normally did 20 to 24 a day if we are weilding around turnouts 12 to 16 if we are doing 110m adjustment weilds or as we called it CWR but if you're just cutting in closures or glue joints in you can pump heaps of them out.
That's wasnt the final grind though that's just the hot grind cause the weld hadnt cooled for long enough plus those lines on the top would be completely ground out plus the running face would be smoother too.
All in all great video though.

I'm fascinated by all the differences in how this is done.

Nice video I’m a thirmit welder and we do things a bit different but nice to see different processes 👍

[itsgenesisttv]

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

[jasonkettles]

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.

Dam, that's a lotta work. Had no idea... Good job guys, thanks for sharing.

[philbogomaz]

You forgot to mention if a cut is needed or stretch depending on the gap, in addition you did not mention the process of aligning the rail at all or packing the mold with sand

[lalitdogra]

Subscribed sir. Thanks for the explanation

[jameschristiansson]

Thermite welders can find work as dentists on the side.

[dfuller]

Didn't know stanley built tools like that!!

[SuperLittleTyke]

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.

[torcheddreadnought]

Thats cool to see. I wish there was a shot of the gap between the two pieces before the weld. Could this be done using other forms of welding?

[Orxenhorf]

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.

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

[justbud]

Thanks very much for this video. That grind could of been better eh lolol

[LelandRogers]

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.

[harrickvharrick]

I'd like to understand how come that slag moves to (those pans at) the sides that easily

[PeteCrutchfield]

If you like this you should see our flash butt welders on the gangs. Its a riot.

[PeteCrutchfield]

The NS does things slightly different. I would say something about those bolt holes but ...
