Can a Join happen with same attribute names, but different domains?

When doing any sort of Join all common attributes are listed under one column in one way or another. However, I have not been able to find a source that deal with columns of the same name, but with different domains.

Put in a visual perspective, I am taking about columns like the case below:

The domain is different because one B column is numbers but the other is letters.


Is a Join possible with attributes of the same name but different domains?
