What Are the Main Uses of Helium Gas?


The primary application for helium is inert protection gas for use in automatic welding. Other applications are that of Helium used as a pressurized gas in liquid propellants for rockets, in the mixture of Helium-Oxygen for divers, as the working fluid in gas-cooled nuclear reactors and as the carrier gas for chemical analyses using gas chromatography.

Helium is used in rocket propulsion, in meteorology, in cryogenics and in breathing operations under high pressure. Helium Cylinder is used as the shielding gas for arc welding as it is non-reactive and allows a constant welding with a high thermal transfer, resulting in high working speeds.

Helium is used as the shielding gas in the arc welding process for materials which are, at the welding temperature, contaminated and degraded by air or nitrogen. Helium may be used in lasers, as even at high temperatures, the gas does not bind to other elements or react.

Helium is therefore used to build the pressure for rockets to be launched into space, pumping gas into fuel tanks. Liquid hydrogen and oxygen are used as the rocket propellants, but once the tanks are empty, helium is needed to empty them. Hydrogen is itself a gentle gas, but the helium bound with a balloon makes it safer to use.

Helium is typically bound with hydrogen via an air balloon. A mix of 80 percent helium and 20 percent oxygen is used as a man-made atmosphere for divers and others working in high-pressure cryogenic applications, such as gas for hypersonic wind tunnels, a shielding gas for semiconductor materials, pressurized liquid-fuel rockets.

Helium Gas for Balloons

Being so lightweight, but still completely inert, helium can be mixed with oxygen to facilitate respiration. Helium gas is used in the inflation of air blimps, balloons used in research, and Helium Gas for Balloons used for celebratory events.

Because helium is a far safer gas to handle than hydrogen, Helium gas is also used to inflate research balloons, and party balloons. Helium gas is used in medicines, in scientific studies, to inflate balloons, party balloons, as well as has applications for welding. Helium other industrial uses as a pressurizing and cleaning gas, a shielding atmosphere for arc welding, and for processes like growing crystals for making silicon wafers--make up half the gas produced. One of helium many industrial uses is preventing chemicals from setting off explosions, which can be incredibly useful for welding.
