    Alu frame repair/welder in Boulder area?

    Can anyone recommend a builder/shop,etc to take a look at my cracked frame and see if it can be repaired? It cracked at a weld.
    Thanks in advance!

    I've always been under the impression that repairing an AL frame is risky.

    You can't repair an aluminum frame its junk. What happens is you reheat treat the area and make it more brittle. It cracked in the first place because the weld was too hot.

    Good excuse to throw away that AL frame and invest in a different material that has more durability.

    This is not entirely true. Aluminum can be re-welded but it must be heat treated again after. If a frame is 6061-T6 to start with (T6 being the level of heat treatment) then welded the area around the weld returns to 6061-0. If its not heat treated again after the repair weld its worthless.
