Quality Control & Manufacturing Process
1. Gas ShieldingArc welding (TIG/MIG)
Optical fiber drawing
Crystal growth
Helium often used as magnesium, zirconium and aluminium, titanium and other metals welding protective gas.
2. Carrier Gas
Gas Chromatographs (GC)
Mass Spectrometry
3. Lift Fields
Airships and advertising blimps
Weather and research balloons
Party balloons (now often using helium-neon mixtures or with recycling)
4. Cryogenics & Superconductivity
Magnet Resonance Imaging (MRI)Particle Accelerators (e.g., LHC)
Nuclear Magnetic Resonance (NMR)
Superconducting Quantum Interference Devices (SQUIDs)
Helium gas widely used in maglev train and medical Nuclear magnetic resonance (NMR) imaging equipment.
5. Pressurization & Purging
Rocket fuel tank pressurization
Breathing gas mixtures for deep-sea diving (trimix)
Leak detection in high-vacuum systems
Atmosphere protection and purging in semiconductor manufacturing.
6. Leak Detection
Automotive AC/fuel tanks/pipeline systems
Aircraft and spacecraft seals
Vacuum equipment
