I have welded a manifold to the head flange with out it being bolted to a head. It's definately preffered to have that extra safety of it not warping but if you do a little section on one runner, then move to the fourth runner and do a little section, then second, then third, then back to one and so on... I have done it w/ 3/8" flanges w/ no problem. (I have a block of 1" thick steel that I check them against, glass works too)

actually, i used to do embrodery (sp) by hand when i was in jr. high. that **** took soooo long to do.

 

hehe its amazing what people can do with their hands when they actually feel like doing it. Everything takes practice. I have actually started practicing welding aluminum with my O/A setup in hopes that it will improve my tig welding.

 

Where are you guys getting your Tig torch kits ? And how much are they ?
I went to Airgas, a local welding supply store, and they were not instock for the size i wanted. Wondering if you guys get them online somwhere....?

 

i do them off blocks... well itake manifolds,,,,, whne they warp i put them on the milling machine with a flycutter and mill them flat, if it sbolted to the head im afraid somethings gonna give cause the heats gotta warp something, you could always get a thick coppers sheet woith the bolt holes to that, like 1" thick and that will suck teh heat

hrmm i think imma see if i can get some aluminum and do that since aluminum is a real good heat sink i was thinking of this get a block of alum drill accordingly to flanges, and submerse the aluminum block in some water and weld everythig above it, therefore dissapating heat as you weld and sucking it out. good idea ?


p.s. where do you guys get your aluminum./ how much and how thick ?

 

al bends fast man, my intake manifolds i make ar eall of AL and they bend real fast, yu gotta mill off liek 1/8"!!!! best bet is copper

so you just need the Alu filer rod right? and what kind of flame and technique do you use?

no, not really. after that company installed his kit the car made less than factory power i believe. just an all around horrible job.

 

who did the install?

AL rod and use a tip size a couple sizes too big and try to make it work

Told ya lol. I used to draw all the time when I was a kid...not saying Im a good welder or anything, but I am saying my hand can be steady when pressed

 

I've looked at this thread many times and seen tons of really good welds. I have the opportunity to borrow a MIG welder from a friend of my father for the winter and some of the spring. I've never welded before and I know I should take a class, but I'm at school right now. There are some kids here that are pretty good at it, so I was going to ask them to show me some stuff. I'm not going to go out and make an exhaust manifold (not yet at least), I just want to mess around and get to know what I am doing. Any suggestions/tips for beginners?

Grab some steel and practise on your own, try it out you might find it comes easy to you.

 

Yeah I've seen the few recent posts about some kind of correlation between welding and drawing, and I think there might be some too (all the hand-eye coordination). I took art classes all throughout high school and almost went to college for it (industrial design probably), but ended up in mechanical engineering. I dunno, drawing just comes easily to me so hopefully this will too. I'll post some pictures of stuff I do as I get better.

EDIT: Fixed, thanks.

Not that it matters but FYI you can delete posts that you make by clicking edit and then instead of clicking on save you can click delete. the post will be removed and your post count is changed.

 

I gotta quick question for you guys: what are you all using to flare your collectors?

 

just curious, would it be not ideal to cool down the welded object with water afterwards ? im not sure if itll prevent warping ot make it even worse. which is it ?

 

If you cool the metal quickly...it will shrink. I bolt my **** up to a thick piece of steel and go from there.

The guy who suggested putting it in water...VERY BAD IDEA!

And for the guy who wondered how we flared collectors...
http://www.burnsstainless.com look for transitions. or..if you need a weak flare go to an exhaust shop..they'll do you up ghetto.

can make warping worse, and make welds brittle and prone to cracking. In the welding industry they have strict codes concerning forced cooling of weldments.

 

i apologize if this has been asked before, but i was looking for a lil Fluxcore/Mig welder to learn with to do all of the above welding....anyone have a good suggestion for a beginner?

I was looking at something like this http://cgi.ebay.com/ebaymotors...sting

I dont get how MIG doesnt need gas...if someone could explain that would be great
