weld prep is critical, just like aluminum there is an oxide layer that will build up on sst. this needs to be removed for a good weld (sst is not anywhere as picky as al but its not like stick welding through paint) get your self some of thesis 7092T14 from mcmaster or your lws. mark one sst and only use it for such. sorry if this is a repeat. watch your cold starts.

MIG welding on mild steel is nearly idiot proof. Now I feel obligated to at least try it out. I'll take some pictures when I am done.
MIG will likely be more prone to leak since MIG welds tend to 'splatter' as opposed to the pooling you get with TIG, but I wish you luck! Anxious to see how it turns out.

weld it.

You can weld, Hobart machines are great m welders, so weld it.
If you worry about porosity & piping in welds there are two solutions:
Take a propane torch to the suspect welds on the day you plan to start the ferment. Heat 'em to about 300F & that'll do it every time. OR use a high flow rate high silver content ( zink & lead free) solder over the welds.

Or get a silver with the least tin you can.
Silver with Zink will melt and flow easier but Zink is not the best in a food app.

Gold would be better but it's pricey stuff for the small amoutn you'll need .

Seriously the propane torch trick is the easiest and most direct.
If you will be using threaded fittings instead of sanitary you'll be taking them apart for cleaning on every brew day anyway. Clean the threads and heat the thing up and poof you are golden. If you use sanitary trt clover fittings you'll have 'em clean and ready for the torch anyway.

I received a mysterious package yesterday. A fellow homebrewer, graciously sent me a 2lb roll of 316 MIG wire, no charge. What a guy!

Hopefully I can begin the experimentation soon. I am tracking down some local plumbing supply shops and an argon tank. As soon as I find a few fittings and some gas... its game on. Pictures to follow. Thanks for all the insight.

That's what I call the brotherhood of welders which there are many including those on the www.millerwelds.com forum.
Call me a cheap bastard I have split 25 pound spools of SS plus spools of alumimum 3 ways with my share as half for my time and labor with refilling the one pound spools on the lathe. The cost savings are well worth the effort and time for us.

It's a piece of cake with the lathe, set the speed than have a friend keep drag on the big spool mounted in the vice across the shop from the lathe on a scratch built ball bearing arbor. With a new clean leather glove i'm tracking like the factory fills. This goes rather quickly less than 2 minutes a one pound spool refill.

Cheap or not... You do what you gotta do sometimes. I don't blame you... welding wire isn't cheap. I hate doing it... but I often end up with cheap tools or cheap materials to get the job done. It is what it is.
