    Default 3mm weld on 1/8 alum

    Hi all

    I've been asked to archive a 3mm tig weld on 1/8th aluminium with 100% penetration.
    I can't go bigger than 3.5 mm.
    There has to be some burn through to be machined off after.

    I don't think this can realistically archived.
    Does any one have any ideas? Can any one do this?
    I been tig welding for 10 years. This is the weirdest project yet.

    Default 3mm weld on 1/8 alum

    Fillet and square groove

    0 prep right now, but I'm trying to get that changed.

    3.5 mm measured the usual way by leg length

    Material is 3003

    Filler 1100

    And using a miller dynasty.
