Same goes for welding... blue titanium welds indicates that the weld was contaminated, generally by oxygen and nitrogen. It is acceptable in some welding specifications, and unacceptable in others. Again, application dependent, but this contamination embrittles titanium, making it less ductile and more likely to crack.

True, but the same would also apply to anodized aluminum which has been widely used for years without causing significant issues.
