how to welding thin SS foil (0.002")?

Leak proof joints in high pressure liquid systems operating at elevated temperatures are made with welded flexible omega-seals that may be as thin as 0.002 inches.

Hi Doug,

Thanks for the info!
If possible, could you point me to an example of such weldable omega seal?
Also, do you know how are those thin seals are welded?

Thank you!

Sorry, I used them rather than installing them. The best known formed the seal between the head and vessel of the reactors that I tested.

I got a bunch of likely hits from a search.
