Adding Studs to weldments for easy assembly

Hi all

I have a question regarding construction with weldments. We are undergoing a change in the process in our workshop. One thing we have been thinking of, is getting all of our welded tubes 3D laser cutted. Along with this it would be nice to add the posibility of adding little stud in one tube and a hole in the other tube for easy assembly.

My question here is if there as of today, exist any kinds of software, feature or something else to help this process?
