Re: Please read this. Very Important !
Mike and others,
There exists a process called "Electron Beam Welding".
Which has been in existence for over 25 years in the Space Industry.
This process is so amazing that Almost any two objects of the same coeficient of expansion can be fused into a permanent welded joint.
I have seen back then Toolsteel welded without change in temper, No annealing, no Quenching,Just a slight micro- puddling of the material along the Welded Joint.
I use the term materiali in its broadest sense.
I have seen certain grades of quarts glass welded to Iron and then the iron welded to inconell, To form a High temprature thermal window for the space shuttle.
It was used to allow certain thermal instruments to look out during the re-entry phase of de-orbiting the Spacecraft.
Certainly after this long a time this process must be finding commercial applications and would be well worth looking into.
