ALright I just had some cheap polished piping given to me. And since my car is down Im gonna be changing my some of my intercooler piping and my BOV location. Anyways here is a pic of the piping its just cheap stuff that Im guessing is aluminum but what is gonna be required to weld a steel BOV to this cheap piping?

 

a tig welder u can't weld steel to aluminum

 

So it cant be done or its gonna require a tig welder??

I dont really know alot at all about welding so that is why Im asking of course.

 

you definetly need a tig welder you should be able to cut it and moc it all up to fit and mark it and take it to a welding shop ,what kind of blow off valve do you have

 

Its my stock SR20DET BOV. They are alot like the 1G DSM bov they even use the same flange. It will hold all the boost that my little turbo produces or it has up till this point.

 

You can't get an aftermarket aluminum flange for it

 

Well while I was out looking at my car I was just running some ideas through my head on what I want to do and Im gonna be relocating my BOV to another spot which is piping that I got from JC Whitney and Im thinking that it will be alot easier to weld the falnge to that rather than that polished stuff?

 

You can't weld aluminum to steel, if you could you would be a billionaire ten times over

 

well he did say he thinks its aluminum, so it could be steel. If it scratches easy, or if you can leave a deep scratch with a pocketknife, then its aluminum. it its thin, like 16 gauge, then its most likely stainless.

 

Does the piping get attracted to a magnet? damn..... i am a genius.

That would only tell you if it's mild steel, not stainless.

 

if it is aluminum, you'll never weld steel to it- however, if it's stainless, go ahead and mig or tig it

This is more like a bond,,,, #1 i don't think he has the cash to try this out(Neither do i ,,I'm not putting him down), #2 that pipe would fall apart #3it's not really a weld because you are not causing the two metals to truly mix it just cant happen. #4 just go out and buy a new flange.....BTW thanks for the link that was interesting

 

Friction welding is welding, and the metals are truly welded together. Just pointing out what can be done with technology, not that it is feasible in this application because of costs and what not.

 

You got me

 

But my statement is still true "YOU can't weld aluminum to steel" lol

Under those terms noone can weld because a machine would still be providing the arc.

 

good point .....lmao

 

Thats a killer little animation!

When all else fails, JB weld!

There is no arc when performing friction stir welding.

 

Aluminum can be welded to steel 24 hours a day 7 days a week all it takes is a High Freq. Box on a Tig Machine.....

Sure, now take that piece the you just welded, heat and cool it a few times. Then when it cools, bend it and see how well it holds.

JB weld works too....but not for ****.

High frequency doesn't make any difference as far as welding carbon steel to aluminum. All it does is help to restart the arc after each time the amperage goes to zero. You can actually weld aluminum on AC without high freqency...the arc just isn't as smooth.

used it on my BOV flange which was steel to my i/c piping which was aluminum... held 7psi no problem for a few months.

my buddy had an aluminum flange to a piece of steel pipe with JB weld on his shadow... 25+psi held for 2 years zero problems.
