    Default Welding a copper fence

    I've gathered from elsewhere in the forum that copper can indeed be welded. I'm thinking of making a fence, part of which would be copper, to give some privacy and security to the deck above my garage. The copper panels would consist of 48"x48" copper "flat bar" frames and curved copper rods of various lengths attached to the frame and each other in some random/artistic way. Ideally, the curved pieces would be solid copper rods, but so far I've only found expensive pure copper rods that are not intended to be heated or welded. Let's start with the basics. Is there any hope for my idea or should I go back to the drawing board? By the way, my long standing connection to welding is having a security door "welding guy" located next to my upholstery shop for 20 years. Ambitious little bugger, ain't I? Thanks for any help/direction you can give.

    Cool

    Are you using Mig, TIG or ox/act torch? Bob http://www.crownalloys.com/products.htm See Crown Deoxidized Copper under the Product header

    Thumbs down welding a copper fence

    Ah, let me get back to you on that. In fact, I may have access to more than one type of welding equipment, but I want to be accurate here. This may take a min as the folks with the answers are sleeping, as we speak.

    I would think making it out of copper would be cost prohibitive, unless you have a place where you can source some cheaply. I've been wanting to scrounge up some copper sheet to make a few projects, but what I've found is very expensive.

    You might make the copper pieces out of steel, easier and cheaper to accomplish, and then have them plated; they'll go green anyway.

    copper can be welded by tig.
    You can strip the insulation of of solid strand copper wire and clean it with alcohol and use it for filler wire.
    I tried it and it works.
    I still need more practice with it to get settings right.
    Too bad that my local jr.college doesn't have a class for this.
    I would be the first one in line.

    I have mig welded copper to steel. But, like everyone has said the cost is going to be very high. I got a piece of 18 inch square copper 1/8 inch thick and it was $80.00.

    Here is a pic of copper to steel (plow disk) These welds were ground down since they are wok handles. (decorative, they get HOT) the copper acts as a heat sink, so you have to play with the settings.

    Brazing might be easier w/copper - don't need to get it so hot. But the joints need to fit pretty good. Guy who mentioned thieves was right on. Heavy duty shears will cut a lot of copper...

    I recommend not using wire for your welding rod. Use the correct stuff (Deoxidized Copper) for best results.
