I doubt you'll find many, if any for Ti...
From what I've seen it's possible with Al for castings as the arcs so intense it blasts the oxide...
But for Ti it needs to be treated with respect as it's low density in comparison to both steel and Al plus the increased reactivity at elevated temperatures means it'd be difficult at best...
Ti has special properties as a transition element that steel, or iron, can't sustain and Al can't as it forms an oxide out of preference...
Ti will react with the compounds used in the flux coating of rods in an arc environment and react rapidly with the atmosphere as if the shielding wasn't even there...

Titanium??
Blueprint for Success
High-purity argon; clean work areas free of combustible grinding debris; the white-glove treatment after thorough cleaning; well-designed and -maintained purges on both sides of the part to distribute the argon evenly; and the technique of holding the torch in place until the metal has cooled below 500 degrees F should produce a clean, silver-colored titanium weld every time. Use 100% Argon!!!! I've witnessed Titanium being welded in a vac-chamber. If you think aluminum is a pain, try titanium! Even microscopic debris will cause problems.
