titanium help
hi I found a local welder to do the bypass mod on my ti cat backs.
does enyone know what kind of titanium is used in the muffler system. he would like to know what kind of rod to use otherwise he will use a all Purpose rod thanks paul

When they weld titanium at work its done in s vacuum .
Military grade or pure will catch fire in high temps .
We have fire extinguishers at work made for metal fires .
I ask our welder at work and he said its
Coated with titanium . ( titanium coated finish )Any mild rod should work .
Or it's not pure titanium Only a percentage in the muffler is titanium .
(A mix )

The company that constructed the Ti mufflers is TIMET
Here is an article about the company, the metal and the product.
In it, it mentions that it used exhaust grade 2 Ti Metal. The PDF has a data sheet for all their products:

The TIMET exhaust
grade is a version of commercially pure titanium
similar to industrial Grade 2. It is produced at the
Morgantown, PA facility
Grade 2 data sheet:

Hope this helps.

Ti in our muffler is pure Ti metal. It can easily be welded if you have the correct Wire, welding tips, shield gas and the set up to purge the pipe.
The shield gas is used to remove the OXYGEN from the weld arc and molten metal. The shield gas has to be on the outside and inside of the welded pipe/muffler. Ti doesn't catch fire. It oxides very readily in oxygen and turns into slag (BIG HOLE) if shield gas isn't properly surrounding the weld.

I know MAGNESIUM will catch fire and when it burns it is super bright white.
Titanium does not. Like I stated previously, It has to have an ARGON Shield gas to purge out the oxygen and nitrogen in the air when it is welded.
If you don't use shield gas, the weld gets contaminated, brittle and weak. It also can burn through and crumble.
If you can find me an article in GOOGLE on Ti fires, I will surely read it..
Here are two of the best TIG Welders out there on welding Ti metal.
MR TIG!
Oh,,,, Here's a MAGNESIUM FIRE!!

I was machining it today on a lathe . Chips from a finish pass .002 ( like steel wool )
Will burn with a bic lighter . When machining you need to keep cutters sharp if they get dull
Friction can start a fire . And you need Fire extinguishing made for metals .
I have seen this happen . I don't think a car exhaust would get a hot enough to do this .
Unless a drive shaft was rubbing on it or dragging on the pavement and even then doubtful .
Turbine engines have caught on fire because of the titanium parts failing ( friction )
