I was reading up (was very bored here at the moment as I am working away from home) about making frames, and it seems the welding on Ti needs to be done very carefully with the purging with argon being bang on otherwise the material around the weld can become contaminated, it changes colour but this can be polished out so you will never know if it is a bad weld or not if buying a frame after they have “cleaned” it, this can cause the area around the weld to fail, rewelding will not cure that weakness, maybe that is why so many “cheaper” ti frames are failing. however if it is well made by craftsmen and engineers then it should be very strong and robust… I am hoping my enigma is the latter 🙂 as I have a lot of faith in their name and ethos.
