Well, even though the only welder I have is a Hobart 140 I decided to try and make an equal length manifold anyway. I think it came out ok for the most part. Hopefully with more time I can get my mig beads more consistant. All the welds done were continuous welds for the most part. No "making beads" Everthing is sch 10. Collector I got precut from Legend boy Instead of shaving it to fit I put a transistion in since the gt flange is so much smaller than the T3. One big mistake I made was not tacking the other side of the collector when welding the 2 halves together. It sucked the other side right apart. So I had to extend on to one center runner and shave the other when I put everything back together It also made the collector not fit together as good as when I first mocked everything up.
Tri-mix was used and .030 308L stainless wire. I used about 3/4 of a can of anti spatter Stuff smells terrible and sticks to everything. I had the runners to flange TIG'd and the transistion TIG'd by a buddy. Hopefully everything holds up... Thanks for looking.

 

the one weld looks a little undercut, but you get my respect for trying it with the migger.


I love mig

 

Looks nice, and major props for the thumbnailed images

I was playing with a MIG for the first time the last couple of days doing my exhaust, I gotta give for doing a manifold with one

 

Looks good, mig don't get a lot of love but you still can accomplish a lot of things with it.

aint that the truth

 

i think it looks great man, why is everyone so down on the mig welders, **** its all i have!

 

nice welds!

because appearance and strenght-wise tig have the upper hand.

Apperance I will give to tig, but there was never any test to proove tig is stronger. I feel if mig is done correctly, it can be just as strong.

 

Thanks guys I'll let you know how long it lasts before there is a crack anywhere. And if it does crack, I'll just reweld it I really need to order up a flex pipe for the dp...

 

Looks nice, for what you had to work with. Hopefully it will hold up well also.

There have been tests done, I'm sure...but I don't think that they proved tig was consistently stronger. The advantage to tig is that you normally have more precise control over the weld puddle, which will usually give you a greater chance of a SOLID weld with no trapped cavities or other discontinuities.

So I think you're right...I just wanted to add to it a bit.

 

nice job, do you find stainless welds any differnetly than mild? does the puddle form at the same rate?

 

It came out real good. Wrap it with header wrap and tell everyone it cost you a million bucks. lol

 

nate

 

wow thats really nice! props for using the migger, what machine is this BTW and what wire dia. and type
edit: opps i didnt read the whole thing

 

**** i think it looks damn good for just having a mig machine, thats just wht my lod wel,ding teacher said you can make it strong with mig it just wont be as pretty, but hey if it works , why the hell not

Exactly. Thanks guys. It's still going strong. I bought a flex pipe for the dp and am going to weld that in tomorrow.

 

post pics of the final set up for us

 

Looks really good.

I learned to weld from a Miller rep, that had a bachelors degree in welding. He said MIG welds can be just as strong as TIG welds, and for the home enthusiast there's no need for anything more than a good MIG. BTW his MIG beads looked like TIG. MIG heh

Neat...but I don't know of any place that has a 4 yr degree in welding. Odds are, this guy is simpy full of ****. IF he has a degree in Welding Engineering, he's likely not going to take a job selling welding machines, he'd go for an engineering job that paid about 3 times the money.

But, yes, a mig weld CAN be as strong as a tig. The problem is that MIG, although easier to do for a beginner, it is harder to get a sound weld with it, especially when welding multiple passes. Not only that, but when you're doing things like the manifolds that most here want to do, it's virtually impossible to get a good solid, 100% penetration weld. Personally, if you gabe me a manifold and wanted me to weld it with a mig, I'd have to bet money against my getting an x-ray quality weld.

In other words, there's a big difference in a welding process being capable of doing something, versus the human being able to do it.

 

How about just having the root pass done with Tig and then finishing up the rest with MIG? Just thinking about the DIY guy who can't pay the $$ for a good welder to do it the right way - root pass + additional passes as necessary.
any reason why you couldn't do the root passes + additional with a MIG on schedule 40 2.5" pipe?

I have been toying with the idea of making my own manifold but all I have access to is a MIG. The options would be do the cutting, fitting, tack welding myself and
1) sending it off to a welder I know and asking him to weld it up,
2) Asking him to just do the root passes with TIG and MIG'ing the rest myself
3) Do it all with MIG, root pass +

 

It's possible to do it like that....but if you're gonna pay somebody to do the hardest part, you might as well give him a few more dollars to do it all....giving a nicer appearance, and better chance of a sound weld.

There's many jobs in which pipe is welded with tig on the root and then stick welded the rest of the way out. However, the most common is that on piping 2" and under, it's tig welded all the way. This is because stick welding it is very difficult. Mig is even more difficult.
