what kind of welding equip do you use?

[z3ds]

I'll be replacing my exhaust this july. Most of the exhaust setup I really like is too expensive for me so i thought that making my own will cost less even if i buy a welder for the project. After doing some research I came up with MIG welding and fluxcored welding techniques. I kind of like the fluxcored one bec i dont need a bottle of shielding gas.

Has any body of you guys used the fluxcored process in fixing up your exhaust?

i use tig, but that dosent help you...i would recommmend one of those tiny mig welders (meant for thin sheet metal) to make an exhaust

My neighbor has been teaching me to weld over the last few months.

I've done gas welding, Mig and now Tig. In my noobie opinion, Mig is the way to go. Sure, if you're good at all three, Tig looks the best and puts the least amount of heat into the part but the metal must fit together really well if you're not too good at welding.

I've blown through a few joints and had to gas weld the holes - it was ugly.

With Mig, it didn't take much practice and my welds had good penetration and looked pretty good too - if that matters to you.

Unless you're doing aluminum, I suggest Mig.

And kudos to you for wanting to do it yourself! Way to go!

Um TIG puts more heat into the job as you have to heat a general area. MIG is much more direct heat. Thats why MIG causes less warpage.

And I would just go and get a small bottle of gas and just use normal wire, its cheaper in the long run, (unless you have to weld outside). The fluxcore wire is a bit fragile and can cause problems with the wire feed.

MIG is the way to go for general exhaust work, can weld all metals (mild and stainless steel and alloy) with it, although alloy MIG welding is a bit messy.

thats not what i have experienced

[Borat]

yeah I know, I have heard other people say that TIG puts less heat in as well. In the uni breaks I work at a motorbike exhaust/repair factory. My boss has been welding for 30 years, I quizzed him on it and he swears MIG puts less heat into the job, straight up guy who really knows his shit so I'm not gonna argue with him.

[Mr Deagle]

im not arguing, but in my expirence (tig, mig, oxy acetaline) tig is the best/cleanest/coolest weling

No way.

MIG is the way to go when putting together exhaust systems.

A good welder costs $$. I think I have over 1K into my Miller 140 (110V setup) with bottle. Go with a bottle as it will be more versitile. I should have went with a 220 unit, someday I will upgrade. I can weld up to 3/16 plate with good penetration. Too much more and it can't quite handle it. The duty cycle is also low.

[Borat]

No way.

hmmm, the way mt boss explained it sounded right. Care to explain why he's wrong?

[matt]

Because TIG puts much less heat into the work. It also gives you much finer control over the amount of heat and the location of the heat.

You don't have to heat a general area with TIG, that's dead fucking wrong. Maybe he's thinking of gas welding.

^^ correct

Borat - No harm, no foul.;-) May I suggest that, when posting opinions of others, you might want to make it clear your post is just that - someone else's opinion.

As you can see from my original post:
1) I am the guy doing the welding so I base my opinion on my experiences.
2) I make it clear that I am new to welding.
3) I'm not afraid to admit I'm not that good at it yet.

I'm sure your boss is a far better welder than I am and I respect his observation although it differs from mine.

Maybe I'll lay down a MIG weld and a TIG weld on the same piece of sheet metal and look at the heat each leaves in the metal.

i would say tig is colder just for the fact it is used to weld aluminum, or maybe its the other way around
