Hi :).. you can make pretty welds that don't break in the first place, but most frame builders welders / designers cant aren't pro engineers so cant tell the difference or figure out why they fail, or understand the modus operand of fatigue in Titanium and the material properties to prevent that...

Put it another way speaking as a professional engineer the frames I build DONT break, designed to race off road for 20 years and NEVER break.

Ladies, this is what your lovely little pretty welds do on a mainstream titanium frame - from an engineering perspective they are not good or strong welds or designs - so break, catastrophically fail in fatigue, have a good evening 👍

these are fixes of badly designed but nice pretty ti frames. Pretty welding is easy, but with these fixes, you have to put material back on to create the strength to prevent it failing again

here are some titanium frame design failures and fixes: https://www.ewhurstbikes.com/#ti enjoy ladies

yes that a pretty crap photo, reflects all over the place, but put aside the photo reflecting all over tte place, lovely welding. & thats not titanium, its very special material. far better than Ti

Hi Cajjy, nothing low buge and low class, thanks, whilst informal, i am a professional engineer with huge experience of titanium and the flaws in frame designs, fixing all of the main manufacturers frames, and the existing builders continue to blindly make the same mistakes. So just happy to...

& yes, that is a Ti repair to a badly damaged Ti seat post, and the bottom bracket we welded of the Alpine Race Sport, that's NOT titanium, far nicer material.

hi thanks for that advice, we are not short of work, i will look at website navigation etc, most of our work is via referrals

we convert alot of them to disc, although the best Raleigh race/mtb Ti frames are very rare now

We have found the grade of Ti in those 1990s Raleigh SP ti frames, is some of the best i have never seen a fatigue failure on any of those frames now 35 years old, lovely material to weld too. Modern grades of ti fail in fatigue nearly always in 3 years if used hard - 10 years lightly used, shot...

Hi we repair a lot of such titanium failures, that's a common failure, looks like an impact followed by crack propagation in fatigue. Definitely don't ride it that once the cracking in titanium like that has started it will propagate very quickly. Its easily fixed although it takes time to jig/...

hi yes we are frame designers and builders, whilst we repair a lot of titanium frames, we don't advocate the characteristics of titanium generally unless its a specific grade and we alloy our repairs to that grade when we repair titanium. we build bikes out of a far better material 1.5 - 2x...

we have repaired a lot of titanium frames for years, they often need design changes where they have failed, which as engineers we have plenty of experience of fixing and of the weird characteristic of the material, and how it fails catastrophically in fatigue

Ewhurstbikes.com have done hundreds of titanium, aluminum, steel welding and carbon frame repairs. As hard core endurance frame builders, and as professional engineers we find that the design features of the frames cause failures, so need resolving, The design of titanium frames in particular...
