broken frame Iron Horse MKIII

[swimfanswimfan]

I welding my broken frame 2 times,
frame broke after 5 ride.
Is it special method to welding this part? I don't why this frame broken in this place?

Ive always been told that once aluminum breaks - done; barring a whole lot of gusset work, time to look for a new ride.

Glad to be proven wrong tho.

beacuse you need to heat treat it. Its still soft after you weld.

You need to provide some gussetting. What's happening is the frame stiffness at the weld junction is increased dramatically, concentrating all the stress right at the weld heat affected zone, so you need to provide some triangular gussets that provide an increase in stiffness gradually towards the joint.

It is perfectly possible to make it work and never break again. I've gusseted and welded my 06' spec enduro non-drive side chain stay after breaking the original, then the new one with the specialized gusset in the wrong place and after that cracked, now it's holding fine after almost a year.

You mostly hear about cracked rear triangles on those bikes, it should be easy to find an un-cracked front triangle.

This is a good point. I bet there must by a ton of fronts to be had...

I've managed to not break mine yet... *knocks wood*

They're great bikes.

You mean done with a perfectly civil exchange in the v10 thread? No I'm probably not. Not sure how it makes me a giant blubbering idiot arsehole, but I'm sure you would know.
