[AT] Welding Rails

[James Peck]

Steve's clip was not exothermic welding, it uses mold halves to contain the powder which would prevent the mushrooming we saw.

Electricians use Cadweld products to weld copper grounding cable to building steel.

I think I remember a clip of Chileans exothermic welding rails together in place.
