Like the man stated NO. Unless whe're talking about the welder screwing-up here so the answer as it pertains to the material is no on account of Titanium's fatigue rate is practically incalculable. They been tryin' to break it for years under thousands of tests, aircraft and otherwise. Even the Russian stuff is good.
The OP's referring to a mid-90s, to my knowlege very few "bad" frames were sold. I know of one and only one that's been disparaged, even that's questionable. Don't know the brand, can't vouch for the welder. Perhaps only the OP will state such.
One things for sure, Ti creates enormous controversy here at the forums.
