Doug is experimenting with using 12 gauge Romex copper wire to weld copper pieces. So far, so good!

I use romex on all copper work because when the finish work and patina work is all said and done, it matches the parent metal. Use something else if you want it to look like a radiator shop welded it.

Nice copper work! Yes, matching materials is the goal. We made another video continuing our experiments: kzbin.info/www/bejne/onfIYniYmK2jfJI Thanks for you comment and for watching.

Use silicone bronze rod, works well. Same stuff you TIG braze with.

I like it 👍 Good job brother 👍

so what youre missing is the flux, if you flux your metals then hit it with the torch itll work, it also looks like youre too cold

If you use a phospho-copper rod for brazing your will get a more fluid puddle for better penetration. Make sure you have adequate gas flow but not too much. Hope this helps.

You want deoxidized copper rod.

Try a flux and see if the porosity disappears... Messing around with unconventional stuff is great fun.
@paulmeersa7162Ай бұрын
Might want to try AC too for extra cleaning, might make a difference to the porosity, and, add less filler - and/or, try pulse to get it to wash in better...

I don't see any porosity.

@@darenscott1718 About an inch along from the start, by the clamp anvils...6 pores, and again by the end of the bead, another 6 pores.... Dirt, loss of shield, not using deoxidised filler or basemetal etc etc. A flux may help?

@@paulmeersa7162ok, now I see it. That's a shielding gas problem with this particular joint set up. The gas is heavier than air so wants to flow down the joint away from the puddle. Turning up the cfh will help eliminate that. If this were a fillet weld the gas would be trapped at the weld puddle and there would be no porosity. Using flux would likely make the problem worse, or cause other problems, when using the TIG process.

is it possible to stick or wire feed mig weld with copper?
@rogue8137Ай бұрын
Depending on the alloy, it is. Used for high intensity busbar joints.

Thanks to all for your feedback. Let us know if you have tried this, please pass along any tips, we will keep experimenting!

I have done this using a syncrowave or oxy/ act. It is possible to get the appearance good with romex. Great for the first try.
