To bond together, two nuclei must be thrown together with great force. This is because every nucleus has a positive charge and the nuclei repel each other when they come close. If that resistance is overcome and the nuclei actually begin to impact each other, then it is possible for one proton in one nucleus to change to a neutron and bind or 'fuse' together with the other nucleus.

The great force required here includes both extreme heat and extreme pressure, comparable to that inside stars.
