Hindustan Gases & Welding

Cryogenics:

• As a coolant for superconducting magnets, especially in MRI machines (due to low boiling point)

Lifting Gas:

• Safer alternative to hydrogen in balloons and airships

Welding Shield Gas:

• Inert gas shield in arc welding (especially for reactive metals like aluminum and titanium)

Leak Detection:

• Helium is used to detect leaks in high-vacuum systems

Breathing Mixtures:

• Mixed with oxygen for deep-sea diving (Heliox), reducing nitrogen narcosis

Semiconductors & Fiber Optics:

• Used in manufacturing processes requiring an inert atmosphere
