hi, I have a tiny crack (about 15mm) on my seatclamp and seat tube. The seat clamp looks like a regular one but its part of the frame. I've been ringing around a few places and Bob Jackson's said something about having to have the whole frame heat treated after its welded...the crack isnt in a structural area and its been there for 4 years and hasnt gotten any worse. the seatpost slips by a few mm every couple of weeks but apart from that there's no problem. i want to get it welded as im going to have it resprayed and want to restore it to its original state
can anyone shed anymore light on welding aluminium? cheers
