Has anyone ever seen this!

I am concerned!
... can you contact the maker?Akirasho

... the main concern for Ti is an oxygen free weld area... I'm no expert, but it looks as though some form of contamination occured...

I'd send the pic to the makers and let them decide.

Be the bike.

If you are not satisfied with the manufacturere's response, you could have that weld X-rayed. Look around for a local fuel tank or boiler inspection service. That would prove whether the weld was good or not.

Still, it is slightly flawed-maybe they'll send you a new one. It seems that a small bit of the weld material didn't quite seat on the headtube. This would be a minor glitch in the manufacturing process.
From what you've shown, I see a weld that is most likely only compromised by maybe 25% right at that immediate location, leaving you with a weld that, in it's entirety, is 99.9% as strong as expected.
Its what I cant see that concerns me!the bull

I am going to keep an eye on this spot!
There might be seperation all along the seam here and it is just on the edge of the one weld were it has com of the tube.

i would say that the welder did not completely melt that area when making his pass. it looks to me like it will be fine because although it's a high spot the individual weld bead looks completely fused. you could grind the high spot down, but that might ruin the finish. apart from the ugly welding, (i can say that, i'm a welder by trade...) it should function fine. although being a welder...i wouldn't have picked that bike just because of the might want to complain to the company for kicks.
was it always that way, or something new? nmDougSloan

Could it have always been that way and when you had the paint on the frame it filled it in? I would think that if a weld was separating it would be over a larger area.
Going to keep an eye on it for now.the bull

If it grows then I will send it back to Tennesee.

Do watch regularly, Ti has a reputation for running once it starts. I've got one on a Tenn Bike 1cm long, downtube on an ultimate. Litespeeds answer is "send it back through your dealer". I sent them pretty pictures too.
