    R1150RT Exhaust Welding

    There was a lot of good discussion of welding techniques in the "Bolts" thread.

    I'm probably going to add a second bung to my exhaust system (R1150RT) so that I can run both a stock O2 sensor and my wideband O2 sensor side-by-side. I don't know any welders in the Metrowest Boston area nor do I know what I'm looking for--skills, equipment, etc.

    Does anyone have a recommendation of a welder in my area who does neat work or could you point out what I would need to ask? Also, does anyone have any thought on where I should locate a second sensor (I would only use the mount temporarily?

    Find your nearest welding supply store and ask the guy behind the counter. He'll know which of his customers to send you to for any type of work. I did this when I needed an aluminum plate welded to the intake of my race car.

    Ideally you would want to have that TIG welded Roger, TIG will give you the neatest appearance on thin metal. If you were stuck and I thought MIG welding would give you the best results, I'd have you stop by. I don't know any of the welders in MetroWest but the poster that mentioned checking with a welding supply has a good idea. Chances are that there is an AirGas in your area. Good luck. Gary

    Buy a bung and plug at an auto parts store. Advance has them.

    If you can't find a welder, send it to me. I'll tig it in. If you want to run with the o2 sensor out, then you can just install the plug.

    110 volt Mig with .023 wire should weld it in fine.

    I don't know if you could find a stainless steel one.

    Many thanks for the replies. I'll start to look and ask around for someone with a TIG welding capability. I've got a bung that came with the O2 sensor but its a deep bung so I will go the the parts store and get a bung plug combo.

    I'm not sure about the exhaust or bung materials. Will there be any welding compatibility issues?

    A steel bung can be welded to a chrome exhaust. A steel bung can be welded to Stainless exhaust, but the
    bung will rust and so will the weld. Stainless bung and stainless exhaust need to be welded with pure argon
    shielding gas (tig) and stainless filler. They will not rust.

    So yes any bung can be welded to any exhaust. Some will be prettier than others.

    Thanks so much David. I wouldn't have thought about the rusting. Could those parts be effectively painted if not SS? There isn't any rusting of my existing bung that I'm aware of so I guess it's SS?

    Innovate, the makers of the Wideband kit make a SS combo that Amazon sells for under $10. Thanks for the tip.
