[Closed] Welding a sheared Alu frame

Hi,

I have a Salsa Spearfish, which I absolutely love. Unfortunately, the seat tube sheared on a ride recently... right above the main suspension pivot.

I was going to get it welded from a chap that seems very good and seemed to suggest the weld would be ok. But talking to a friend, I am begging to wonder if it will hold.

Any experience of having a seat tube welded that went ok? The bike is 6066 aluminium and I don't think the guy would be heat treating it after TIG welding.

Thanks,

Chris
