ive seen this question before but i searched and couldnt find an answer can you mig a manifold how much of a difference would there be between tiging and miging. would you be able to mig a good quality manifold or no. can anyone show the differnces between a migd and tigd manifold

thanks

 

you CAN mig it but I really wouldnt.... The welds wont come out nearly as clean, tight spaces will be very hard to weld and its harder to weld stuff like stainless or aluminium

 

IMHO... If you have a decent MIG welder the manifold will be just as sound. Hell, I have even made suspension parts with MIG. Structurally it is fine. However you will never be able to get that sweet rainbow-colored stacked coin look with MIG.

 

beepy what kind of metal are u using to make manifolds? and what size?

 

I got a friend that MIGs his Nissan 300zx headers all the time, looks like total *** but it works, 636whp He uses mild steel. Just make sure you do a leak down test....although you should do that with TIG too.

 

I use sch10 stainless and various mild steels. Beveled edges, 2 passes, with 0.028" wire. 75/25 mix gas. I get a little higher crown with stainless, but after some practice I think my welds are looking decent.

Of course, my next leap may be to buy a TIG.

 

pulsed mig, no spatter

brokeback mountain?

lolz, but MIG is fine. If you don't care about the bling bling look, the MIG will be perfectly fine.

 

Ok, I'm outta here. Someone said brokeback mountain. lol

 

can you use a 110V MIG (with gas shielding) to weld manifolds is the question id like to know

 

I would not reccomend it. But if you went to home made turbo they would praise you like a god. Wich would be sweet. Cuz home made turbo rules

 

tig is better, but ive seen a mig manifold personally handle 280+whp on a d-series and last a few years and still is on the car today.

my thoughts exactly

 

I used an old 90amp 110v miller to do mine. Cranked up the voltage and the manifold has been holding(no braces) my holset turbo for a year so far and makes 270whp.

 

I have made a lot of sch 40 mild steel manifolds with my lincoln110 MIG. They come out pretty nice and none have ever broken that Im aware of.

 

what kind of machines are u guys using to do this?

when you say 2 passes, do you mean you go over the seams with filler then braze over it?

 

I've miged a sch. 40 MS ram horn, turned out fine. The hardest part was using a 110V welder w/a 20% duty cycle ...a lot of down time.

Cause you changed your legal name like 18 times... just kidding. I remember your work with the mig gun, good stuff.

Yes you can mig a manifold, will you get laid with putting down a mig weld.... aww probably not, girls love the color.

Then again ManBearPig4silly is pretty desperate these days
