Why Can't Titanium Rings Be Fixed If Broke ?
« on: 23/09/2007 17:19:03 »
Dear Sirs/Madams/Others!

I know Titanium is an industrial metal that is very hard. But why is is that if a ring is made from it that if is breaks it can NOT be fixed ?...if It's split or chipped it can not be repaired...whysthatthen ?

Thanks

neil

All I know is that titanium is very difficult to weld.  See also the quote from Wikipedia (http://en.wikipedia.org/wiki/Titanium) :
Quote
Titanium burns when heated in air 610 C (1,130 F) or higher, forming titanium dioxide.[6] It is also one of the few elements that burns in pure nitrogen gas (it burns at 800 C or 1,472 F and forms titanium nitride, which causes embrittlement).
(The melting point is much higher than 610C or 800C)
Still, if they can build bicycle frames from titanium, it must be somehow possible to fix a broken ring (at a cost).

Yes....yes I am sure you are right Mr Eric Sir. THANK YOU for your answer.

I imagine then that although the ability is there to create with Titanium, perhaps, specifically as something as small as a ring, that it's not cost effective.

Thanks Mr Eric

Titanium welding requires particular technics, but not so complicated or expensive.

Arc welding:
TIG (tungsten inert gas)
MIG (metal inert gas)
PAW (plasma arc welding)

Power Beam Processes:
laser or electrons beam

Resistance welding

Friction Welding

Diffusion

Forgering

Soldering

...

Grazie Mr Lightarrow Sir.


Hmmm..does seem a lot of work involved just to fix a little ring !

So, it's not as simple as just melting the thing down again?

But that's not so much 'fixing' the ring as completely remaking it.  I think that's the main problem.  Any attempt at fixing the ring is likely to destroy the ring.
