    Sound like you will need a company that specialises in titanium welding.
    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.

    I will ask around at home to see if they know someone in ireland that can weld titanium.

    Titanium is very specialised. It needs to be welded in an inert (usually argon) environment. IF you were to weld it, I would tack it after surrounding the material with argon (TIG). You would need to let it cool after each tack. Ti is really difficult to deal with and oxidises (burns) above a certain temperature in oxygen. It is high unadvisable to even do this however!

    I'm having the same problem with a few motorbike exhaust pipes, the best a local enginnering shop could do was braze the pipe. The results were not to bad, of course it wont be as strong as a proper titanium weld but it will witstand a lot of force. I eventually broke the brazed joint, but that was after dropping the bike:rolleyes:
