Aerospace: Helium is widely used in the aerospace and aircraft manufacturing industries from manufacturing to flight. Space flight operations use helium to purify hydrogen systems, and ground and flight fluid systems use it as a pressurizer. In addition, helium is used as a source of lift for meteorological and other observation balloons.
2. Automotive and transportation equipment: Helium is used in the testing of critical automotive components such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure that they meet quality specifications. In addition, helium can be used in conjunction with argon and is increasingly used in airbag inflation operations.
3. Diving: When diving, nitrogen narcosis can be effectively eliminated by combining the use of oxygen and helium, reducing breathing resistance at depth and shortening decompression stops. The helium-oxygen mixture allows the diver to stay deeper in the water for longer periods of time. The deeper the dive, the higher the helium concentration, the deeper the diver can go and the longer the weld time can be achieved.
4, electronics: helium plays an important role in the manufacture of semiconductors, liquid crystal panels and fiber optic wires, enabling rapid cooling of components to increase productivity and control the rate of heat transfer to improve productivity and reduce defects; in addition, helium can also be used as a carrier gas in the production process.
5. Healthcare: As the ideal cryogenic gas for magnetic **** vibration and nuclear **** vibration superconducting magnets, helium can achieve deep freezing temperatures of -451 degrees Fahrenheit, effectively obtaining high-resolution images of internal organs and tissues.
6, welding and metal processing: helium in the arc temperature conditions of inertia makes it become aluminum, stainless steel, copper and magnesium alloys and other high thermal conductivity of the ideal gas welding materials, but also can be used as a quenching gas in the heat treatment process, as well as furnace gas, to enhance the parts resistance and quality.
