Basically because both nuclei are positively charged so repel each other.
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
Fusion. When a nucleus splits into two or more fragments this is called Fission.
nuclear fission (if the atomic nuclei are broken into smaller lighter elements) nuclear fusion (if the nuclei fuse to form a heavier element)
If you mean covalent bonding...well then they bonded.
..particles (nuclei) fuse together to form heavier nuclei. Initially, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, lots of energy is released.

It is the nulei which fuse. Nuclei are positively charged and thus repel each other. The kinetic energy of the nuclei must be very large for nuclei to be able to fuse, such as at the surface of the sun, where hydrogen nuclei fuse to form helium nuclei.

Hydrogen nuclei (protons) fuse together and produce helium nuclei

Two nuclei fuse together to form another element
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
Where people fuse two atoms together to make the nuclei heavier
