    Thumbs down Is the weld separating / cracking on my litespeed frame?!!!? (see pic)

    Hi I have a litespeed titanium frame and was wondering this is cracking by the welds. I believe it is but I'm not experienced in this stuff. It looks like the weld is a bit raised in comparison to the other side on one end and possible very small cracking near it all around...I'm not 100% positive but believe this is where a possible creak is coming from which I thought I eliminated but decided to do a really thorough check of everything and found this. I found this hard to spot but getting a close up shot with the camera makes it seem real obvious I guess:

    Kind of hard to judge without knowing the frame.

    If it’s seperating, it should visually open when you stress the frame in a direction stressing the weld.

    What about the little tiny looking cracks around the weld. I don't see that on any of the other welds around the frame.

    I'd need to look under at lest 10x power to give you any opinion.

    Email some detailed photos to Litespeed and ask them.

    Can you catch an edge in the area that looks like a crack?

    I think you’re looking at a shitty weld. The cracks I’ve seen in titanium weren’t at the welds like in your pics, they were across the welds and often around the circumference of the tube.

    I would go to a reputable bike shop (one that doesn't just want to sell you another bike) and have them check it out. That is preferable to getting advice on the internet from people like us who have nothing to base our findings on other than a photo. Seriously.

    This.

    Use a dental pick to try and catch an edge.

    It appears to be lack of fusion as the top layer of weld did not bond to the bottom side. From the pictures it appears that there is a root or under layer of weld. If you have no warrranty, Find a great weld shop that welds exotics (like titanium) and have the weld repaired, should not cost more than a couple hundred but stress to them the importance of heat control to prevent distortion of your frame.

    By the way,, good shops have dye penetrant kits and will check for cracks before and after the repair weld.. I would ask to see the final check..

    It doesn't look like cracking to me. Looks like the edge of the weld doesn't have penetration.
    The rest of the weld could be perfectly fine (most likely the case). Or it could indicate a poor weld and potential future issue (but I doubt it).

    There's no way to further diagnose that weld from a photo. Personally, I wouldn't think twice about riding that.

    The only way a crack would develop there would be if the frame saw movement there.

    Paint the area with some colored fingernail polish and go for a ride or two. If the fingernail polish develops cracks then yes, your frame is cracked.

    Obviously, you can remove the fingernail polish at any time.

    A good reason for ground welds. A crack will be obvious, as well a a crappy penetration.

    With the quality of the photo, who knows?
    Don't put the crack in a shadow, or is that a shadow?
    I'll bet it's a shadow.

    What exactly will a reputable bike shop do? I doubt they have weld experts there. Or can do xray or dye penetrant examination.
    They're just going to refer him to the manufacturer. Especially if he didn't buy it there.

    They will let him know whether they think it's an issue or not. That's it. My point is in-person advice by an expert is far better than advice from anonymous people on the internet who have nothing to go by other than photos.

    In all my times going to bike shops, I've never met a metallurgy expert, or a welding expert.

    The majority of the employees are high school and college aged kids who I wouldn't trust with assessing a damaged bike frame.

    There are non-destructive techniques that can be used to assess the integrity of that weld, but you will probably have to take it to a business that deals with that sort of thing (aircraft/airframe maintenance shops come to mind).

    Me either.

    Heck, I design welded structures for a living. And we've got some pretty darn good welders. Infinitely more knowledge than you'd ever find in a bike shop.
    But none of us could just look at that weld and tell you much other than "there's no way to tell by looking at it".
