So what’s “cold welding?”

[Jonty30]

When you place two metals together in the vaccuum of space, they just join together. It’s almost like they pass between each other’s atoms.

[Mogger]

This needs to be brought into practical use as soon as possible.

With affirmative action and multicultural engineers being hired and other grads with very little knowledge, but great self esteem, poorly designed disasters will be waiting to happen.

But if the metal can heal itself, perhaps the destruction poor number crunching and stupid designs cause can be avoided.

[Jonty30]

This a pretty good explanation of cold welding in a vaccuum.
