Exothermic welding creates a permanent molecular bond in seconds.

That's how they weld train tracks too. They use a canister of thermite that burns hot enough to melt steel.

Yup. We call it cad welding

40 Years we called it CAD welding -- I don't actually know why we called it that we just did.

The best example of this I have seen is welding train track rails together.

When your mold gets a little worn and that angry liquid plasma comes out at your legs is when the real fun begins!

Thermite reactions creating seamless, super-strong copper bonds in exothermic grounding welds share core chemistry with frontier lunar tech. Researchers are harnessing these self-propagating exothermic processes with regolith in simulated vacuum to produce construction materials on the Moon turning local dust into durable infrastructure. Combustion chamber designed to simulate the lunar environment, showing the high-information experimental apparatus used for testing thermite reactions with NASA lunar regolith simulant to sinter dust into strong construction materials on-site.

Same stuff they used on 9/11 🎯🤡

We used "thermite" devices to weld the wires on the border control systems back in the 80s.

The steel has lost his strength through this welding.

I seriously doubt this is as strong and durable as uninterrupted woven metal strings along the entire length. Source: common sense.

A blowtorch is plenty practical, sure, but why don’t you try burning the shit out of your hand with this bad boy.

Endothermic would be even cooler! ;)

Ground grid?

As a TIG welder, that is the ugliest weld i've ever seen.

Used those to ground our cell towers

It's brazing, not welding. The 2 metals are attached with a dissimilar metal.

Basically rust and aluminium powder

Thermit

Thermite no only blow up locks ..... you can fusion stuff.

Thermite welding has been around forever. I've got an Audels Welders Guide that was reprinted in 1942 that explains it.

That is the stupidest idea I've ever seen. Gross inefficiency, dubious practicality.

@VishakhRanotra @prakdadlani

Its a dime and some gunpowder. 🤷🙄

Where the play dough around the mold lol

Same stuff used in WTC 1,2,7 🎯

Clear welding method

Just use an irreversible crimp.

Biz elektrikçiler bilir cad welding yöntemini Türkçesi cadweld kaynağıdır.

I feel like this was a little fluffed out for hype. Any kind of welding (not including “liquid weld” epoxy) by definition causes a permanent molecular bond, but exothermic welding does that in seconds.

Pyriet

Cool demo

Fun fact, this was created in ww2 to destroy nazi cannons from inside.
