Yes. Hydrogen atoms fuse together to form helium - releasing heat as a by-product. The helium atoms migrate from the centre of the sun to its surface - reverting back to hydrogen as they do so. The cycle repeats itself.
Helium is produced by fusion in the interior of the Sun.
The energy of the Sun is produced by nuclear fusion - the fusion of hydrogen into helium.
Nuclear fusion.
Through nuclear fusion of hydrogen to form helium
Nuclear fusion in the sun's core, where Hydrogen-1 is converted to Helium-4 plus energy.
Helium
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
Most of the energy of the sun is usually produced as a result of the nuclear fusion on hydrogen into helium in the core of the sun.
The nuclear fusion of hydrogen into helium. The mass of the helium produced is slightly less than the mass of the hydrogen used to make it and this mass difference is released as energy (E=MC(squared)).

If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
