My three cryo cars.


Before BLI released their cars, I built my own!

Thank you gabby very much. All I have is build photos, not very instructive! My tablet is giving me fits, it takes forever to post anything!
 
They hauled liquid Argon at -302°F. Argon is used in chip mfg and mig welding.
Also Tig (Tungsten Inert Gas) welding, used largely for welding Stainless steel (done a lot of that). The process is very similar to Oxy-Acetylene welding, where you have a "torch" that produces a "flame" and a hand held and applied, filler wire is used sometimes, or just fusion of the parent metals. The difference being is it's not the gas that is ignited to create the heat, but an electrical arc, between the sharpened tungsten rod, clamped in the torch, the Argon gas flowing from a ceramic shield at the end, to keep oxygen away from the arc. The Tungsten rod does not become part of the welded joint, as in "stick" welding though.
