umm im thinking of doing a turbo manifold out of titanium (i get it for free). how hard is it to weld?

is there any benifit to using this material over any other material besides the fact that i get it for free?

 

in order to get a "pure" weld, you need to have it completely cut off from oxygen i believe. i've heard of people welding it underwater, any a guy i know has a chamber he welds Ti in that fills up with helium i believe, and he wears a breathing apparatus.

 

good lord! sounds like to much work. i think ill pass.. thanks though.

 

i've had first hand experience welding titanium in open air....and you can make some hot looking welds by just experimenting a bit, but they are still contaminated welds. seemed plenty strong to me, but the guy who was teaching me about it said that by welding them in a sealed environment, they get MUCH MUCH MUCH stronger, like leaps and bounds stronger. i dont ever see myself working with Ti, but i still wish i would have paid attention to what gas and wire and heat level we used to weld it.

 

Ti is a soft metal especially with some heat, so depending on how hot you beleive the manifold will get will depend on if it would be worth it. And yes for a quality bond you will have to form a Vaccum chamber to seal off the O2 from burning the metal...

 

if the mcleran f1 can use a ti's headers and possibly formula one(im not sure)
im sure itll be fine for a turbo mani

Titanium annelas at lower temps than stainless steel so its not really any good for Turbo manifold. If the maclaren F1 was turbocharged you would see Stainless 321 grade Manifolds.

Titanium is an extremly light weight and failry strong material. the problem being is that it's heat properties aren't up to par especially if you were to use for a turbo manifold. It would just crack and eventuall fail all togther.

Ti is not especially hard to weld, the puddle is rumored to flow very easily like a nice clean stainless.

Titanium however works great for under car exhausts where the egt's are low enough for it too survive.

F1 headers are made from inconel

Agreed the headers are usually .015 to .019 thick

 

I've welded Ti, it's really not much different than stainless except having to keep oxygen from the weld. Tubing isn't hard cause you can purge it good, but brackets and such are hard without the proper purge setup.

 

Ditto's the above comments. We (our welders) do it at work (day job) in a glovebox with inert atmosphere.
