    Factory pipe cracked expansion chamber flange-need advice

    750 wet pipe.
    Flange on expansion chamber for silicone coupler cracked where it was originally welded in production.

    Should I have this welded or use jb weld. I have filed it down and can see the start and stop of the weld

    I think jb would hold but if it were mine I'd bring it to a shop and tell them how you want it to be fixed.
    Don't ask them if they can fix it, tell them how to fix it.

    I like this. Anyone in a production environment recognizes a never fail mindset. If you don't give an option of failure it happens much less

    That will be very expensive to fix. It will take a couple hours of cleaning first to get it ready to weld. All that carbon caked oily mess will contaminate the weld. They will charge you plenty for that, clean it first. I would soak it for a day in solvent or degreaser first to break down the oil. Then clamp it to something and powerwash it. Then bead blast eveything within a few inches of the area needing repair. Then heat it up with a propane torch and wash off with brake clean and repeat to sweat out any remaining oils from the metal. Then finally its ready for welding.

    I don't like the idea of jb weld. Might hold for short but then a pita to clean it up for welding.

    Thx. That's the advice I'm looking for.
