Default Welding Stainless with MIG?

I have become reasonably proficient using my MIG welder on mild steel using the flux wire filler. And i always assumed that welding a stainless fitting to one of my precious stainless pots was not possible with my MIG setup. I figured it needed to be TIG and you needed to be really good with it (experienced).

Anyhow, I recently noticed that Stainless is available in the 2 lb spools and that they even make stainless with flux in it - presumably so no shielding gas is required. My MIG welder does have gas capability so I can do the shielding gas if needed. And i have plenty of CO2 as well...

Obviously I will need to get some scrap stainless to practice on.

So the big question to you welding experts; Is it possible to get good results welding stainless with MIG equipment?

Thanks! It is now brew thirty and time for a beer

I would definitely get some gas for it. It won't look as good as TIG but it will work.

You can do a search for stainless welding on here. Here is a thread. My reply is #7. It references some other threads. If you're going to do this, you need to read them all. Luck, and let us know how it goes - Dwain

the cost of the spool is about $20 for a 2lb, you can hae the fittings tigged for close to the same price, but it looks like you would have to buy a bottle and regulator as ell so having a shop tifg them would be much cheaper and better quality

I used a mig welder on all my keggles, and they turned out ok. I used solid wire and shielding gas. I didn't use any back gas, so the inside looks crappy and rusted a little to begin with, but it is fine now and since none of this is in contact with cool wort I didn't worry about bad surfaces inside. If you want the inside to be good, you need to back gas the weld area. It took a while to get the welder settings right because they were very different from what I would use on mild steel of the same size, so practice a bunch first on scrap.

You want either argon gas or an argon/helium mix.

The best gas for stainless is a tri-mix, but costs more.

A more economical gas is O-1(99%Argon1%Oxygen)

Helium increases the heat input which may not be a good idea on sheetmetal.

Helium is normally used for welding thick sections, and increased travels speeds

go with gas and use tri mix it is 90% Heilium 7.5% Argon and 2.5 C02and it works pretty well I have done stainless mig welding many moons ago.
