Hello,
I have a very challenging welding problem and need help. Following are the issues and parameters.
We have a device that has two small chambers, each of which contains pressurized (15 psi)very low viscosity fluid (solvent).
The concept includes the mixing of two liquids to form a highly detectible gas to indicate when electrical equipment has overheated. The device is completely mechanical, very small 2"dia.x3"), and we have chosen to use a foil sealed opening that can be pierced by a spring charged plunger.
It is imperative that the liquids in the two containers do not leak as they are highly detectible by the gas sensor. The problem we are having is how to make the foil sealed opening. Welding is the only method we consider reliable for sealing so we need to design a foil orifice that, perhaps consists of two washers with the foil sandwiched between and welded at the edges. That is the path we are pursuing but I am certainly open to any ideas or referrals.
Thanks

Don't jump to quick to EB. It is a relatively expensive process. You should consider btrueblood's suggestion or maybe the lazer weld.
