Have you looked at using...

Analysis -> Model Compare...

thanks for advice to use Analysis and model compare. Yest this is good but not permanently. When I close the window I need do this analasys one more time. I want to have result for all time. It is possible to make this two parts in one part which will be intersection of them?

I don't see a reason why you couldn't do this manually.
Unite, subtract and intersect might help you out.

Why don't you just do a File -> Import -> Part? Take file #2 and import it into file #1.

Careful with that. If these are native NX parts, you will end up with both part histories in the same file. That might be what you want, but more likely will just lead to a big mess. If model compare isn't good enough and you want to subtract or intersect the 2 parts, I would suggest using associative copies of the bodies (via promotions or wave links).
