I have just purchased all of my material and flanges to weld up a manifold. I do not have a back purge set up although I can set one up. I have read up on it and its received pretty good reviews. Now, I am just not sure if anyone has used it on turbo manifolds and if it works well on schedule 10 pipe. Would the residue that it leaves behind be something to be worried about in terms of it breaking off and doing any kind of damage to the turbo? I would much rather go this route instead of dealing with back purging but if it is not worth it I will back purge it. The manifold will be for personal use and not for anyone else. Here is a link to their site... http://www.solarflux.com/Pages/Howtouse.html

 

wtf!!?? are you on weldingweb web?

 

Nope. I remember someone mentioned using it on here a while ago but yeah I also googled it and read a couple threads on weldingweb. Whats wrong with welding web LOL. And no, I am not registered on the forum.

 

i think this is the link you are talking about.

^^^ Thats the one! What do you think about it?

 

i never used it but like David said you will not be able to remove all the the glass paste residue after welding.

 

oh well i was just talking about it and asking if anyone used it on manifolds.. so it was just wierd how u made this thread the same time i did

 

My friend uses it, It does a good job. I don't see a problem cleaning the inside of the manifold when your done. Just use a engine cleaning brush to get inside the runner.

 

i used it once. it is hard to clean and break the residue off in the 90 degree bends. it worked really well for the sch40 i was using but i didnt like the uncertinaty of it being able to break off so i went to a backpurge set up as soon as i had the money. but if you are doing this one time and you have the time to work on getting the residue off then it will work great. it works good for exhaust also. btw it is a little messy

 

how you gunna clean the inside of a runner with a brush on this....

 

very carefully maybe? i got no clue. it would be one hell of a bitch

 

Go for it.

After you make one manifold having to mix up that horrible black mud and smear it onto the inside of every friggin joint backpurging will seem very convenient.

 

could be a dumb question, iv never used it, how do you apply it inside the runners? i take it you just spread it around the ends then tack the joint together right? i cant think of any other way, iv also heard that if it sits too long, after drying it has a tendency to flake off.. is that true?

 

Have you seen those monkeys on discovery channel smear their turds on stuff to mark it? Yeah, like that.

Seriously though, it is a power you mix into a paste, then you brush/smear a layer on the inside of the joint you plan to weld.

 

Yes, it does flake off after a while so you have to weld it within a day or so. I just use a brush to apply it.

The glass it forms is pretty much just like the slag you'd get using flux-core or stick welding. Tough to get off unless you use a chipping hammer. That's why I only use it on turbo-back exhausts or on full N/A setups.

 

i use backin-flux its half the price of solar flux.i just did some .035 stainless headers today.this stuff just falls off after your done.you can tap it on the table and it will just fall off.or use a pipe cleaner to run down the tubes.

 

Can I get the backin-flux at AirGas?

At this point, I am not planning on making more than one manifold or pretty much anything that will need to be backpurged. From what I hear it works pretty good other than it leaving that residue. I will just spend the time taking the residue off when I'm done.

 

i got mine from united welding supply in portland oregon.i think if you try your independent welding shops you will have better luck finding it.i think you will be fine.take your time cleaning it off.i find that if you are not over welding it.the glass like stuff will not form on the back and its just a dust to nock off when your done.
