(quoted from post at 02:51:13 05/09/19) How may of you have been affected by this crunch on helium gas supply's.? Was at the local welding supply store and he got a call on the phone from somebody fishing looking for a cylinder of helium. Government has put the screws on it.
Helium is used for TIG.(quoted from post at 09:39:39 05/10/19) Any welding supply I ever went to offered argon . I don't remember welding with helium . Maybe one tank .

(quoted from post at 14:36:47 05/14/19) . We use helium as a cover gas above the moderator water in the reactors. Prevents the entry of oxygen , nitrogen and other gasses . Prevents corrosion and reduces radition from oxygen 16 and nitrogen 19.
Helium is also pumped into vessels then the vessels, seals and fittings are sniffed to find leaks .

We use hydrogen as our cover gas in the reactor coolant system when at power, and to cool the generator, just gotta keep it pure. We have used helium for leak detection in the steam condensers as well as sf6.
