I have a Ti ring as well and ran into the same problem. I also have experience with Titanium.

The ring is machined and not molded out of molten metal like traditional gold and silver rings thus adding/deleting material to resize is not possible.

The next thing is that while titanium can be welded it is extremely difficult and would not yield good results on something like a ring.

Final is that it can be cut off if needs be with a dremel wheel. I have cute 8th inch titanium with a dremel wheel before and although it takes a little longer it will work.
