I heard, and I hope it is not correct, that Argon as used in inert gas welding is running out. There are several countries that are hoarding many hundreds of tonnes, (if not thousands of Tonnes) as they are trying to safeguard their industries.
It is similar with Helium and other inert gasses. If this is true, many businesses who produce gasses for welding and other industrial applications will be going out of such business of supply. Apparently, recovery of these gasses is almost not possible or not practical, due the very low concentrations contained in the atmosphere.
Making theses gasses may be only option if possible.
If gasses cannot be made and or supplied, what happens to all welding shops, engineering, supplies, and other industries who have no alternative that need shielding gas?.
