opinions on brazing quality please
Hi,
I've recently acquired a fillet brazed frame but I'm not convinced about the brazing around the back of the seat tube / bottom bracket. Also the seat stay bridge looks badly mitred to me (a non-expert). Any opinions on this? Photos link below. http://picasaweb.google.co.uk/113140...eat=directlink |
Looks TIG'ed, not brazed. Looks like a not-bad-but-not-great made in Asia frame.

That is sorta like what an undercut weld looks like, except the concern is normally when it is a highly loaded part, the bead is small, and the undercutting indicated either cutting into the metal or that penetrations was not realized. In this case you sorta have an undercut like look in an excess attached puddle. I don't see a structural problem there. As far as the bridge is concerned I don't see any problem. Are you concerned it seems to be set into the stay? Looking at this on a netbook so I couldn't really see anything. Not a highly loaded part anyway.

the pictures of the bridge aren't really good enough for me to judge what is going on there. The brazing at the bb looks good except it wasn't cleaned up that well. There are no obvious issues with the brazing anywhere.
