Railroad Thermite Welding

submitted by Mordhaus

1 decade 11 months ago

They use Thermite to form the weld because standard welding does not give 100% weld penetration. If you listen carefully, you can hear the ping sound when the rails fully join.

Pretty hardcore alright...This is going to make the trains happy again as well

That is freakin cool.

In Sweden, if anyone is wondering.

When I first read this title, I interpreted it as "We figured out the best way to put these two things together was to blow them the hell up!"

Well... to be exact...

That is freakin cool.

No safety glasses; a little scary that way

Not so. The guy in the black shirt has safety glass on his head. On top of his head. You know, where a hard hat normally goes. Perfectly safe.

Oh, you're right. No need for me to worry about the GLASSES anyway...
LOL
Watch the other guy bang the red hot slag off the rail with the sledge. No glasses on that I can see. Red hot burning metal in your eye.
Plan...

Interesting, must be a fairly constant temperature there.

In my country they welded the rails together to save money on maintenance, which was fine until the next hot summer when they all expanded and buckled.

Really cool.

Why does it make the ping sound when they fully join?

When I first saw this post, I thought it was titled "Railroad Thermite Wedding".
I'm disappointed, but in a good way.
