I want to get this welded but should I?
Hey guys, Ive seen some nasty pics of AF's snapping so Im a tad worried.
Ive just put gen 3 plastics on my gen 2, this has exposed a frame scar where the old radiator shrouds wore in.
I want to get these scars welded over & I will file, sand & polish them out.
My worry is will getting a weld laid over the scar put the integrity of the frame at risk?
Cheers for any advice

I have been to the top of the mountain and yes it is good.
I'd have no fear of problems arising from welding that classic plastic vs alloy groove. It's away from the main stress points within an AF frame, other than the down tube / Y - that is at the points where the spar is welded to the shock tower, the cracks propagate from the inside , then the top , bottom and eventually the outside of the spars with the natural flexing of the spars - your groove is about 80/90mm away, by the looks of the fuzzy picture.
A nice bead of 5039 - best for what I believe is 7000 series alloy, but 5356 is perfectly acceptable ( I use 5356 pretty much exclusively, as it is suitable for all the grades I deal with), by a competent TIG welder, then your choice of finishing tool and off you go.
A little bit of clear contact at touch points goes a long way - I've seen frames , and more often, triple clamps / forks worn all the way through by plastic / cables rubbing against the soft alloy.
I'm using Gen3 shrouds on my alloy tanks, and any edge contact point has a small bit of clear contact on the tank.
