Helium is a colorless, odorless gas with the chemical symbol He and atomic number 2. It’s the lightest of the noble gases and the second-lightest element overall, sitting right after hydrogen. Helium is completely inert and colder as a liquid than anything else in existence, which is why it turns up in medical scanners, leak-testing …

Yes, you can MIG weld without gas, but not by running standard solid wire with the gas turned off. That gives you weak, porous welds every time. Real gasless MIG welding means switching to self-shielded flux-cored wire, which carries its own shielding inside the wire and doesn’t require a separate gas cylinder. WestAir supplies gas …

Liquid hydrogen (LH₂) is used as rocket fuel because it delivers the highest specific impulse (Isp) of any practical chemical rocket fuel, producing more thrust per pound burned than any other option. Paired with liquid oxygen as the oxidizer, it powers upper stages and deep-space missions where every pound of fuel counts. WestAir supplies liquid …
