The Sun's core is not yet hot enough, or under enough pressure, for helium fusion.
Which is probably just as well, since when helium fusion begins, the Sun will swell into a red giant which will incinerate the Earth.
The main by-product of nuclear fusion is helium, which is formed when hydrogen atoms combine under high temperatures and pressures. Additionally, energy in the form of electromagnetic radiation, such as gamma rays, is also released during the fusion process.
In the sun the product of the nuclear fusion is light energy and heat energy. It also created helium from the isotopes deuterium and tritium.
The sun can be described as a nuclear fusion reactor - converting hydrogen into helium under intense heat and pressure.
A hydrogen bomb is a nuclear fusion weapon, and it is powered by the energy release of hydrogen when it is fused into helium. Only under extreme conditions can hydrogen be fused into helium. Helium fusion is, after all, the power source behind the operation of most stars, at least for a large part of their lives. Our sun is but a single example. To create the required energy density to initiate fusion, a fission weapon must be built "around" the fusion elements. This will drive them (the fusion elements) together and initiate fusion, with the resultant release of a massive amount of energy in an extremely short period of time.

Hydrogen is fused into helium in the core of stars through a process called nuclear fusion. This occurs under extreme temperatures and pressures, allowing hydrogen atoms to combine to form helium, releasing a tremendous amount of energy in the form of radiation.

Helium is a noble gas with very low boiling and melting points, making it difficult to compress into a liquid form. It remains a gas even under high pressure due to its low molecular weight and weak intermolecular forces.
The element created in the center of stars through nuclear fusion is primarily helium. Initially, hydrogen fuses together to form helium under the extreme pressure and temperature conditions within a star's core.
Nuclear fusion is the process that supplies the energy for stars. In the core of a star, hydrogen atoms combine to form helium through fusion reactions, releasing large amounts of energy in the form of light and heat.
Hydrogen fusion. The hydrogen atoms in the core of the sun are under such intense pressure that they combine to form helium and energy.
The Sun is hotter because it is made of hydrogen under high temperature and pressures that is being slowly converted to helium in a nuclear fusion process.
