I don't think You need to get to complicated. Somes Rags and Duct Tape and just keep a little positive presure on the inside. But Your really going to need 2 bottles and regulators. Titainium is suposed to be just that much more important to keep Air out off when welded. In the cold war I understand that the Russian Subs could dive deeper because they had better Ti Welds than ours. The way they did it was to have an air tight building and then purge all the air out and replace it with gas. Then the welders went in with life suport systems of there own. Needless to say they lost a couple of Welders but they had good welds ! I have seen SS Pipe welded where a second guy holds a small screen on the end of a Argon hose and he just holds it close to the inside of the weld as the weld was being done on the out side. The Welds looked perfect.
You're right, rags and duct tape would be a lot cheaper than what I was thinking of using. I thought of plugging the inlets and outlets with multiple turbocharger boost leak tester plugs ($24 each) so five of them would be $120 (already have one).
Superior responded yesterday and suggested I use a distributor that carries their flux. Nearest dealer is in Augusta, GA so I'll be calling them. Superior will direct-ship me a one pound package of their 9H flux for $50 plus $5 (small order surcharge) plus shipping -- if the place in Georgia isn't willing to ship it to me.
I have a spare regulator so the rags, tape and second source of Argon is doable. Cyberweld will ship me a full 40CF tank of Argon for $165 and I should be able to find a spot for a fourth cylinder in the garage.
Because they have huge deposits of titanium ore, Russia (Soviet Union) was able to make their submarine hulls using titanium alloys. Far as I know, the US stuck to steel alloys for our submarine hulls. An argon-filled manufacturing building sounds like something they would do. A step up from the salt mines.
