Hey Chevy,
You're getting some good replies, but it seems kind of sporadic, so I'll put in my two cents...
Yes you can weld the stainless exhaust with SS solid wire and 75/25 gas, BUT, it will look like crap because the edges of the weld won't tie in very well with the pipe and the arc is hard to control for making an even bead. When MIGing SS, I like to use 98% Argon / 2% Oxy because it works a lot better.
So, yes, it would be a good idea to get a small bottle of 98/2 for MIGing SS to SS. And, no, you won't have to put anything on the weld to protect it.
Keep in mind though that the natural anti-corrosion properties of the SS on the inside of the exhaust pipe will hold up better if you purge the inside of the pipe before and during welding. Usually, pure Argon is used for purging because it's cheaper, but that doesn't mean that you HAVE to get a third bottle. You could just attach a "Y" splitter to your 98/2 hose and purge with it.
Also, yes, you can weld mild steel with the 98/2, BUT, it will look like crap because the edges of the weld won't tie in very well and the arc is hard to control for making an even bead.
For the SS to CS gate weld, use 309 SS wire and 75/25, and yes, you will have to put a protective coating on the weld to keep it from rusting.
Another thing to keep in mind when welding SS to CS steel is that there is a side-effect called dissimilar metal electrolysis. This causes the weld joint between the two dissimilar metals to corrode faster than the rest of the weldment, or in this case, gate. That doesn't meant that your gate is gonna fall apart at the seams right away, but if you're using thin wall tubing, it might not last longer than a year or two.
Good Luck!
Tim

If building a still tower in stainless, what about the weldings are they ok no matter what you use, or do I also have to be aware what's poisonous hereHope some knows how to help Last edited by rad on Wed Nov 16, 7:42 am, edited 1 time in total.

Re: Stainless welding ???
Are you referring to the weld itself, or the fumes created by the welding process...???Re: Stainless welding ???
Stainless welds and or brazing are all fine. I often MIG and TIG stainless using stainless wire or rod. You can use silicon bronze rod to TIG stainless to copper. It is safe. The only solder that will work with stainless is Silver solder so no issues there either.Go forth and build !!!!

Hey MR how do you MIG stainless? I have a MIG welder but I was under the impression I couldn't do a decent stainless weld with it. Are you using a specific gas/wire combo? If this could save me from investing in another tool I would be very appreciative.
Re: Stainless welding ???
You can buy Stainless wire to run in your mig machine and it works great as long as everything is cleanCoyote "Slow Down , You'll get a more harmonious outcome"

Thanks NC, I thought I'd have to change the bottle along with the spool. If I can successfully do this at home that would be great, save me some money also.
Re: Stainless welding ???
The guys are fast. They have answered your question.Yes, you use a tri mix helium gas and stainless wire. It works great. No, Really great. The helium gas is very hot so it makes for a very sweet weld. Easy!
I keep a stainless mix bottle and change out gas and wire when I want to weld stainless. I like it better than TIG welding stainless. That is probably because my MIG skills are better. I will use my TIG to clean up some welds sometimes.
TIG welding is often referred as "Gentleman’s welding" because of the ability to do delicate welds. TIG's basically melt metals together. “TIG Torch” Great for some things like welding corners together where you can run down the weld melting two pieces together. When doing more conventional type of welding where material is added like welding rod or wire feed TIG’s take more skills. Stick or MIG apply material as you arc.
TIG is more like torch welding where you have to add filler rod as you proceed. Except you cant pull back the flame quite as easily. I have great respect for guys that are TIG masters.
You will love MIG stainless!!!

Re: Stainless welding ???
Mash:(not trying to hijack this thread)
I have a Lincoln 175 (220 volt) MIG welder. I use the CO2/Argon mix and solid core wire.
If I picked up a bottle of straight argon, and a pound of stainless wire, then I could MIG stainless?
Any way to MIG stainless to copper? I've done it with Oxy/Acet, but that was a long time ago.
Bull. Life is hard, it's harder when you're stupid...
Re: Stainless welding ???
I've never tried MIG with stainless, TIG comes up well. This one is fused with TIG, could use filler rod and then grind down, polish and you can't even see the join unless you look inside the tube.- Attachments

Thanks MR I'll have to give it a go, a little more investment in tooling but lot cheaper than a TIG unit for sure.

Yes, you can weld stainless with your MIG but not very well with straight argon. It is a hotter helium mix that you will need. If you want to weld stainless to mild steel it is a different stainless wire than stainless to stainless. Tell your welding store what you want to do and they will make sure you have the right wire and gas.
Stainless to copper? I don’t know. I believe you can TIG them with silicon bronze rod so maybe they make a silicon bronze wire??? I have tried welding copper to copper with argon and really struggled. If I had to do it I would want to try the hotter gas and short welds letting the heat dissipate.
On the subject of joining metals, I silver soldered some stainless last weekend. I bought some special stainless flux. I was only successful with soft silver. I could not get hard silver to flow.
I tinned two pieces using the flux and just barley enough heat to coat the surface. Any excess heat just burned off the flux and I had to start over. I then used regular water base flux to get the two pieces to join. It worked pretty well.
(Wait until you see that new design)
NWVapors. Do it cheap. Next time you are out of gas just exchange for stainless gas and buy a small roll of wire. The hotter gas will work for your mild steel. It is more expensive gas so you wouldnt want to buy it every time for mild steel though.

Re: Stainless welding ???
With TIG if you want stainless to copper use 316 stainless filler wire, copper to copper use copper filler wire and I have had no problems with argon. You need to be quick with copper as soon as you see the weld pool form be ready to start your run real quick. You also need a lot of amps.Re: Stainless welding ???

Re: Stainless welding ???
Here is a thread I participated in a while back when I was taking a TIG class at a local junior college. This member was TIGing copper and responded pretty helpfully to questions.http://homedistiller.org/forum/viewtopi ... 32&t=
Re: Stainless welding ???
MR I have been playing around trying to hard silver solder also,it not as easy as soft solder. I have a buddy that works HVAC and he said silver solder will not flow like soft does, so put it on and smooth out with the flame of torch, I did watch him and he made it look easy, but I guess it is going to take practice. It is what you make itRe: Stainless welding ???
I have no problem with hard soldering copper, brass or steel. I love the stuff there. Stainless steel is a pain in the ass. The flux seems to burn off before I get a flow temp. I am careful to use a passive reducing flame and heat indirect but still have problems.Bottom line is that I end up either MIG, TIG or soft soldering stainless. From there I will leave it to the pros.
I am always open for advice.

Re: Stainless welding ???
Ok, to get back on track,....I have nothing poisonous to fear about stainless welding (like when you solder copper),...have I got that right Never argue with an idiot, they will always drag you down to their level and when you are down there, they will beat you with experienceRe: Stainless welding ???
if your speaking of the metal ,no all you do when welding is to melt the base metal and at times add filler of the same or close to the same as the base metal.so if it was safe to start with, then its still safe.with stick/intersheld yes as they use flux that needs to be removed.as with any metal all has to be cleaned well as they use oils and chemicals in manufacture.

Re: Stainless welding ???
yes corrected on spelling,, intersheld and stick use flux. stick is the older type of welding where the wire is covered with flux.. intersheld has the flux inside of a tube and fed threw a gun much like MIG.either of these are generally used on thicker metals but can be used on thinner stock if no other way is available.both of these need to be well cleaned.TIG (tungsten,inert gas) and MIG (metallic inert gas) both need less cleaning.Re: Stainless welding ???
