anyone have any idea or info on making turbo mainfold for a 4afe engine?what kind of weld am i supose to use [mig,tig,arc] what the damn differance anyways??
ive got an arc welder will that work?
your can probably use arc it always gives a nice bead, if u do it right. I think most of them are done that way by the looks of it. I had take welding in H.S., once in summer shcool and in reg. semester. U just have to know what setting to use and the rods as well.
yup, i guess that's how it's done. If you got a plasma cutter and an arc welder handy but u can take the pieces to a local high school and have some punk kid who's really good at welding do it for you.
You dont really need a plasmacutter. Oxy/ace for cutting, or a metal saw and cutting oil. As for welding, you can use Mig/Tig/Arc if you know how to do it. Even oxy/acetylene might work.
i remember the acetylene welder, i damn near blew the welding shop up. I didn't like it much compared to the arc, i can stream line the beads better. I worked with the tig at my dad house trying to do some patchwork on a '69 mustang. I don't think we got the right type of metal gauge wiring for the job 'cause the welds kept coming off after i grinded them down.
You sure he used a Tig to do patchwork rather than a Mig? Mig is wirefed, Tig is basically using electric arc to form a weldpool and then doing it the oxy/ace style and feeding a rod by hand.
Oh and when you said you grinded off teh welds and the parts fell off, that wasnt due to wrong wire, that was due to poor welds, not enough penetration so your old man had the wrong powersetting.
I'd rather do it so that I'd cut out the damaged metal, cut the same shape from sheet and weld that replacing the damaged part as a whole, rather than welding on patches and bondoing them, causes less problems on the long run to do it properly.

So when is this project gonna take place? Now i wanna build my own headers, if i can get ahold of some good material that has a mandrel bending machine and such. I need to fabricate some fog light fixtures for my XRS since i sold the front bumper cover and forgot to take the damn things out.
if you want to make a turbo manifold, use ready made bends, not alot of mandrels can bend 3mm thick piping cold.
Check the tech page I posted. A log manifold would be the easiest option.

Arc is a generic term. If you really think about it most forms of welding use a arc, except for oxy acetylene welding (gas welding).
Most people associate arc welding with stick welding. The correct term is SMAW (shielded metal arc welding).
MIG or GMAW (gas metal arc welding) is a wire feed welder. You either use a solid wire with shielding gas (co2, argon, c25 (75% argon & 25% co2), or tri-mix (co2, argon, and helium)) or flux core wire. Which shielding gas you use depends on the type of wire your using (copper, aluminum, stainless, etc...)
TIG (tungsten inert gas) or GTAW (gas tungsten arc welding) uses a torch (tig torch) with a piece of tungsten. The tungsten provides the arc which is controlled by a foot pedal. TIG welding is similar to oxy acetylene welding in that you use the same technique (move and fill the puddle). Theres different filler rods depending on what your welding.
For a turbo manifold I would use 304SS or 321SS. 321SS is a better choice.
Either mig or tig weld it. Tig would be better, you get better penatration and cleaner welds. However mig is easier.
If you use mig you need a high powered mig welder (220V) with stainless steel wire and tri-mix as a shielding gas.
You can use a 110V mig welder, but you have to run a small wire like .023. If you run a bigger wire like .030 or .035 the welder is not going have enough power to melt the wire.
I took welding in college and I mig and tig weld every now and then. So if you any questions about welding, just ask.
you get the same penetration with mig as with tig, but certainly the welds are more uglier. But I'd do the manifold from seamless NSP pipe which is used in waterpiping for example, the material is thick and it needs to be thick to last. its cost efficient to use steel pipes, instead of stainless.
www.homemadeturbo.com has alot of good articles on turboing, albeit its mostly honda, but the principles are the same.
We dont have 110V here, its 220V for normal outlets and 400V for 3-phase outlet, but I lack 3-phase in my garage.
I had welding courses in school for oxy/ace and mig, but I lack tig, but its easy to learn if you know ace/oxy.
