Broken rim seam?

After my bike fell over after being leant against a wall, I started hearing a slight ticking noise under braking. Investigation showed that the weld seam (?) on the rim was catching very slightly when it passes the brake blocks.

The 'edge' this has produced is very minute, but is this rim unusable now?

    Photo?

    If the weld has given, you need a new rim

    Looks normal to me. If it's bothering you, dress it off with a bit of wet'n'dry.

    NB It's a pinned rim rather than a welded one.

    The rim looks very worn and concave from the photo, which might be the reason it happened for such an insignificant event. My advice is to replace if it makes economic sense.
    I have seen rims going saddle shaped and this is a good candidate. Needless to say, if that happens you will be down on the pavement

    The end of the rim would be curved if the rim were concave. It's straight as a die.

    Plus, there is a clear wear indicator groove running round the centre of the braking track which has plenty left in it.

    Really?

    Hard to tell from a photo; to me it's just picked up a little scoring, but nothing serious.

    It is definitively weakened and being in doubt, I would never advise to ride it.

    Tedious... these look like Mavic or Easton and there is no sensible way for me to rebuild them. Besides, Aksium come as single wheels for 80-90 pounds or so.

    I am giving what I think it's sensible advice, would you put your money on that rim being safe to ride?

    It looks to me as if the joint is failing; the wear indicator groove appears to have a step in it and so does the other scoring.

    At the very least take off the tyre and tube and have a much closer look.

    Are you sure it wasn't making the noise before? Once you see something, you tend to look for change. I can't see how a bike falling over is likely to damage a wheel and the score marks look like there was a discontinuity in the wheel already - they don't line up well so imply that the 'edge' was already there. Might be worth posting a pic of the other side as well.

    I wouldn't bother offering advice based on a poor quality photograph.
