Interesting video - Russia, maybe?

Interesting use of Thermite. I've seen thermite used for cutting thru steel vaults but not for fusion. A mini on-site steel foundry application. Fascinating.

I didn't bother to check before I posted that, and I took the spelling right off the bag - "Thermit." I didn't realize at the time that it was a foreign video. "Thermite" is correct.
I've seen rail workers in this country doing the same thing.

“Thermit” is a company brand name for one of the commercial products available. This is not new but a ‘process’ that has evolved to serve ‘high speed rail’ globally.

FWIW, the lettering _is_ Cyrillic (or Russian, if you like.) I helped develop international keypads for security systems, and Russian was one of the languages.

Thermite welds have been used for many years on American railroads. It comes in bags premixed with iron pellets that melt when it's ignited. The molten metal flows down into the joint and allowed to cool. The cast is taken off and the edges are ground down. That's how the railroads create 1 1/4 mile lengths of ribbon rail from 1/4 miles sections.

I wonder how many sections of 1/4 mile track it would to to make a section 1 1/4 mile long.
I was at a senior lunch one day, and a woman said the woman next to her was going to be 90 next month. I said, "That's great! How old is she now?" It took her a moment to process that.

Back in high school chemistry, myself and my lab partner were tasked with giving the class a demonstration on thermite. I remember using powdered aluminum as a component. To ignite the process we used a section on magnesium ribbon. We did the demonstration out if the school parking lot. It was pretty spectacular.

I'm surprised a teacher would have you use that stuff. The parking lot was a good choice for a location.
