Welding Titanium

[petawawarace]

Anyone here have experience doing this? I have a couple parts I may want to make, as well as modify some Exhaust tubing that's made of Ti. I'm guessing I will have to make a chamber for welding it? Think about using an small benchtop sand blasting cabinet, but looking for other ideas before I go that route.

Thanks

You really don't need a bubble (chamber) for what you are doing. A gas lens and a back purging setup will be just fine.

No need for an inert chamber. Set it up just like stainless with a back purge. Ti is very easy to weld if you have some experience with stainless. It will become slightly magnetized once heated up, so your filler rod will feel like its pulling in the puddle once you get to close.

You need a trailing rig for Ti. It keeps the purge on the weld a few seconds longer to allow for cooling of the weld. Use a #12 gas lens with the trailing purge. Keep a tight weave and you should be good.

Just out of curiosity.......how many people run titanium exhaust? We used it a lot for testing heat exchangers, but never heard of anyone using it on a car.

as far as I knew most really nice racing exhausts are made out of Inconel 625 or the likes. Titanium exhaust must really be up there in terms of price.

My Corvette factory exhaust is titanium, from the axle back.

All the above is correct for Ti welding, same method we use.

Here are a couple pics from when we "enhanced" my stock exhaust.

Basically bridging the inlet to the outlet for some of the exhaust gas during high flow situations,

On the flip side Chevy Volt is also sporting Ti exhaust from the factory.

Been a long time since I did it, but if you pull out to soon the crack will just go for a walk. Keep the cup in place as you come off the pedal.

I'm running a titanium rear section and connecting pipes on my car. It weighs 19lbs vs 58lbs for the factory system.

I ran Ti on my bridgeport 13b turbo. Very light. Took the extremely high heat 1800-2000*F very well never had a manifold crack, cracked a few apex seals but never a manifold. Keith

Lots of options fo those with higher end stuff. Gtr, m5 , vette

Beautiful car and the exhaust is a work of art.
Do you have a build thread?

Thanks for the advice guys. I will give it a shot. It's for a formula car that's getting a ZX-10R transplant. The bike engine already has a very nice Ti exhaust, but I need to re-route it for use in the car.
