[TheForge] Welding advice

[Bruce Freeman]

As I understand it, alloys are produced by adding alloying elements to
the mix.  Thermite produces excess heat, sufficient to melt other metal
powders present.  The obvious limitation on this is that you would not
want to choose metals that would be consumed by the reaction (as is the
aluminum).  I doubt that's a severe limitation.

	I'd considered that.  The only way I can see this as viable,
would be 
to dope the thermit with alloying elements that would, presumably 
produce a filler with the right structural properties, lest the welds 
become weak points.  Thermit produces ultra-hot pure iron.  I cannot 
imagine that pure iron would be nearly strong enough for the duties to

which a battleship would be subjected.  Just think of the stresses due

to the sheer weight of the vessel.  Forget about withstanding the
forced 
of a torpedo or artillery shell.  The welds are the weak link.  And how

would the iron be carburized to the correct level?
