Ok, I'll be the stupid one...

What can you do with a TIG that you can't do with a MIG?

If you were going to prodominently weld mild steel an some stainless, would you buy the TIG or the MIg?

Todd, depends on what you are welding. It would take a long time to Tig a trailer, but an exhaust header would probably be better made with Tig. I think for most general purpose welding that Mig is more useful, whereas the Tig welds will be more attractive and according to many, stronger. I have done a bit of O/A welding in the past, so supposedly Tig would come easier, but I don't have much desire to try it. I like stick and Mig because it is quicker.

First off, Todd, ther are not any stupid or dumb questions, here, and I think you know that

Your first question requires a rather lengthy answer....I leave that to Dan... in short, TIG is cleaner, and you can make smaller neater welds with it...the drawback is it puts more heat into the part and takes longer. TIG is better for stainless...MIG can also weld stainless but is not as pretty.

For fab work the MIG can handle gaps better, and is quicker. If you could only have one...I vote for the MIG.

Nuff said. I thought I might be left out of something. I'll stick to my MM210.

Going to weld some SS tommorrow for the first time.

ROTFLMAO... Good One Rocky D!!!

Of course, I actually do read just about every word that Dan writes... TONS of knowledge...

But it was still funny!!!

Rocky D, Do you use any process other than TIG for aircraft welding? When I was in school ( A&P) they taught us that OA was the only approved process for structural welding. Is that still true?

We do have a spares contract that uses stick on a thrust reverser. and I remember when we used to O/A weld aluminum. We do still O/A for silver brazing, but not for welding anymore. Mainly, it's TIG. You have a A&P licence Duke?

[Royal Fe]

Yep, but never work under it. The information exposure was amazing, from sewing to welding. Notice I didn't say I retained all that information, jsut know where to look it up. Hardest test I ever took.

Don't blame ya...after all there ain't no rebar in airplanes!

You can TIG weld real small and thin stuff that MIG would blow holes in. Try MIG welding razor blades.

Thats it Bill from now on you are going to get nothing but false information from me.

Ouch Rocky

You just stabbed me in the back. I thought we were ganging up on Scott V, and then you go and turn on me. I have to admit that it is quite funny though.

Dan, take it as a compliment, that's the way I did. Maybe its an Oregonian thing to beparanoid.

Rocky, any truth to what I mentioned about Tig being strongest weld? Don't see how.

Cope,

I just read your post, and not to answer for RockyD, but have you ever tried to run a 1/16" fillet weld with a MIG welder? What kind of penetration do you get? Sometimes it's a pain to break loose a piece I have tacked onto a frame using my TIG. Really great penetration.

MIG still wins hands down for speed and "forgiveness" though.

Aaron, I have not run a bead on Tig, but I know its the way to go for thin material. What I mean is on 1/8"-up, is Tig the strongest weld? I would think that stic, especially with a 6010/6011 root pass would be stronger. Obviously for aircraft and other apps, Tig is the way to go, but that's not always because of weld strength.

Dan, I'm just funnin' with ya! I am actually envious that you explain things so well.

I think that to say one was stronger than the other is not true...it depends on the application. It is true that in certain applications one would be stronger than the other. Like what Roger said..ya just don't MIG weld razor blades. I guess, and I'm thinking while I'm writing this, that a TIG weld on 1/8" material would have 100% penetration, while A MIG weld may not. In that case it would seem that a TIG weld would be stronger.....bottom line to answer that question, you just can't make a blanket statement that one is stronger than the other. Does any of this make sense?
