The second lightest element, helium is one of our most precious
natural resources. It will not combine chemically at any
temperature with any other element. It is non-flammable,
non-toxic, and non-explosive. Its chemical inertness makes it
perfect for a variety of applications.
Helium's most common application is as a shielding gas for arc
welding. Because of its high voltage gradient, it transfers more
heat to the weld than does argon at the same arc lengths. This
added heat is essential for high-speed welding.
Itself a product of billions of years of radioactive decay
beneath the earth's surface, helium is not affected by
radiation. Radioactive immunity, along with excellent heat
transfer makes it an ideal heat transfer agent for gas-cooled
nuclear reactor.
