WebJun 15, 2015 · Helium is used in arc welding as a shielding gas because it is non-reactive and allows for a consistent weld at a higher heat transfer, which translates to a higher work speed. Many times, helium is blended with argon gas and the mixture can be adjusted based on the heat, shape of the weld, and speed required by the job. WebHelium-3 (3 He see also helion) is a light, stable isotope of helium with two protons and one neutron (in contrast, the most common isotope, helium-4 has two protons and two neutrons). Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons. Helium-3 was discovered in 1939. Helium-3 …
