good idea or bad idea? how would one go about doing this?
-
with brazing rods or duraflux rods
I might have to give the Druafix rods a try...
I don't have access to a tig to weld up Al charge piping, etc.
-
If you want to use aluminum piping, HTS2000 i think? makes a brazing rod for aluminum. Ived used it to repair broken alternator ears, etc. but only on cast alum. stuff, I havent tried it on like alum. pipe but worth a shot I suppose.
-
yah. thats what i want to try because... well
i mean its not necessary to weld everything. they aren't stressed parts, or structural components, so i figured they'd be ok.
-
As long as it will hold pressure and static testing(wiggle it around and see if you can break it), it will be fine. At the same time, I'd suggest welding it for real. Mild steel and a $100 "MIG" welder would be the best low rent option.
-
Lots of couplers?
wanting to change bov's and intake manifold work.
-
i've seen side car race bike frames that are brazed. i wouln't worry too much about charge piping.
-
Ford used a tubular intake aluminum manifold on one of their I4's in the 90's, and I'm 99% sure it was all brazed together.
-
lol i brazed an adapter plate to an HF manifold and ran it for over a year without it cracking or the turbo falling off. i doubt you will have a problem keeping charge pipes together

Make sure you either use the flux filled rod or flux and the proper filler material. That crap you get at autozone is not it. Good luck and if you have any questions just ask. I am one of the few people in my area that still can do this and every once in a while I get the call to weld something in the field that cannot be welded any other way.
-
cool beans. anything i should know about as far as what kind of torch i need?
-
A good oxy/acetylene torch is about it. You can find victor heads and second hand tanks pretty cheap if you're patient.

It sucks ass on pipe.
-
i use a flux for welding aluminum with OA.
it works great.
not easy tho. you gotta practice at it.

what if i dont want to get an oxy/acetylene setup?

Good to know. When you coming up to north kackalakee?
-
Looks good! I'm going to try it out if I can find some at local stores.

Dont use that durafix shit. All that crap does is contaminate the material so it cannot be welded properly. Use a proper flux filler rod and a oxy/accel torch.
-
Not all of us have the luxury of torches.. as soon as we got a Mig the torches went back (leased)
I just bought some alumaloy (durafix type shit) off of Ebay. I am gonna try it on my intake pipes.
I will pressure test it and report back.. if it sucks I am only out $14 (for 15 rods shipped)
If it works really well .....beer can intake LOL

Im not sure, i was talking about it yesterday though, maybe when you get some snow so i can show you guys how to use a sled. Its needs to happen though :P
When you guys comming down here??

heres one of my first aluminum welded pipes with oxy/acetylene.
its a flux from tm2000. the flux is cheap the rod is cheap. but the goggles are a couple hundred.
the flux burns and puts out a different kind of light.
-
will hold pressure as long as you keep it away from a constant heat source
-
cant i get a butane or mapp gass torch that can heat up to and past 750 degree?

That's a good video. Short, to the point, no BS. I will definitely be trying that shit one day.

The sledding we do involves an 89 civic 4wd wagon, with the sleds tethered behind.
You got 2 couches to crash on? Im not sharing one with JD. :?:

Thats my kind of sleding, i better be notified of an good incomming snow storm.
I got more than enough couchs, few blow up beds, and a fold up roll around.
You guys should come down for the Nscra event in Dec, its going to be a HUGE event. Jd and Goforth flaked on the last one. Maybe even bring stewie along.
Hows the new Pcar 4 door look in person??

Maybe its a little bit small tho lol
I have one and works great on small thing.

cool. saw some of those things at home depot.
i wonder how much they cost.
how where do i order the brazing rods from?

no comments on what else i said, haha

I bought some BernzOmatic brazing rods for aluminium.
It works pretty well on thin sheet. I welded to pepsi can together, but haven't tried on thicker metal for now.

Post pics... My Alumaloy (durafix) came inthe mail today ,i am gonna do a pressure test with some scrap intakes.

Post you results nog.

There is my first try. I didnt really know how to do so result is not super nice. I didn't clean the cans too.
Rod are 3.50$ for 2 so I didnt want to put 1.75 to weld 2 cans together :-\
The trick is to get the pieces you want to weld very hot then put the rod on it. Once the fusion bath is done it's pretty easy to move the rod to weld the pieces together.

actually looks promising.. Wonder if it's just a matter of cleaning the cans.,
Where did you buy the stuff?? I am wondering if Princess auto has it

Canadian Tire, in the welding and soldering section. It comes in bag of 2 rods, but I used like 1/3 of 1 rod to weld the cans together.

-
There was also a little gab between the cans. That's why you can see some hole. Still very strong. I can't brake it even if I strongly twist the can.
-
that looks cool. i wonder if it stays good looking or corrodes.

Alumaloy / Durafix is Fail.. I tried it this weekend along with Ktownpowercoat on an aluminum intake.
it works for pop cans and that's about it.. You need a real torch to get anything thicker then a pop can hot enough to work the material.. We tried both regular propane and the yellow stuff..
neither worked on intake pipe...
so if you want to weld pop cans together this is def the product to get..
-
Yes we did but either of us have tanks :(

Intake pipe made of pop cans, interesting. ;)
I'll buy a oxy-propane torch to see how well it works...

i think most people are using the mapp gas with a torch head like the first pic. but i think it has to be for mapp gas.
i use a two part mapp and oxygen torch for my heavy brazing ok all my brazing. a little butane torch worked for me for doing some real thin sheet metal with flux and silver solder
-
i was thinking of getting this...

hell... do the bbq trick. lite your grill... get it nice and hot... throw it in. wait till it gets hot as fuck... and braze away. saw it on some website about a supercharged wrx?
-
My dad has a set of these (similar to it) baby torch and it works great. It's just annoying because you need to fill them more often.
I've seen the BBQ thing too, it was cool. You could probably just heat up the pieces you want to braze in the BBQ and use a normal torch after that. The problem is that the aluminium is so heat conductor friendly you can't use normal torch without heating it forever.
If you heat it to 200F, I think the normal torch would be enough to heat it at the good temp.
-
If you used lugged/slip brazing like one uses on bike frames it would work great. You can even work with different materials if you go that route like steel lugs/ aluminum pipe but aluminum doesn't braze well and when it's lugged it's usually epoxied.

One of the guys at work talks about slip-brazing his bike frames all the time. WTF is slip brazing?
