Take a mixture of powdered aluminium and iron oxide, ignite it and stand back. Within seconds the mixture flames to twice the temperature of molten steel, and from the bottom of the special crucible comes molten iron. In 1914 Thermit was a cheap simple way to weld heavy iron. The same stuff is used on the solid fuel boosters of the space shuttle.
Learn about the invention of Thermit process, welding rail, special crucible and rail moulds, butt welding of pipes, broken locomotive frames, and much more. You get detailed information on the chemistry involved, how to set and pre-heat pieces, how and why to add nickel or titanium, the use of Thermit in foundry practice, examples including photos of repairs on a torpedo boat rudder, a locomotive frame, even a steam boat paddlewheel axle.
An unusual process, loads of rare information.
