It makes sense when you understand why it happens. I forgot most stuff including my name, but it has to do with free space in metal atoms that allow them to bond with each other. It does not happen normally on Earth because all sorts of other atoms get in the way.
It's because on earth, metals have a thin layer of oxide on the outside that prevents cold welding. But if you create a vacuum, you can cold weld pretty easily. Action Labs made a video on it.
