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.

Kain · « **Reply #3 on:** October 19, 2009, 03:02:22 PM »

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.

patsmx5 · « **Reply #7 on:** October 19, 2009, 04:08:03 PM »

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.

ryan89crx · « **Reply #8 on:** October 19, 2009, 06:47:13 PM »

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?

SgtB · « **Reply #11 on:** October 19, 2009, 09:24:24 PM »

A good oxy/acetylene torch is about it. You can find victor heads and second hand tanks pretty cheap if you're patient.

Looks good! I'm going to try it out if I can find some at local stores.

Durafix Aluminum Welding Rods

slappynuts · « **Reply #17 on:** October 20, 2009, 10:13:55 AM »

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.

Lowerit · « **Reply #18 on:** October 20, 2009, 12:23:47 PM »

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

When you guys comming down here??

toyolla86 · « **Reply #20 on:** October 20, 2009, 12:57:39 PM »

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.

colt45 · « **Reply #21 on:** October 20, 2009, 02:03:26 PM »

will hold pressure as long as you keep it away from a constant heat source

Kain · « **Reply #22 on:** October 20, 2009, 03:31:35 PM »

cant i get a butane or mapp gass torch that can heat up to and past 750 degree?

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??
