fixing brass egr tube

Quick question on my dd I couldnt get my egr tube un bolted from my intake or exhaust...so I had to cut it so that I could remove my intake. Well now I need to mend the two pieces back together...@first I thought I was gonna solder it with a repair sleeve,but then I thought about it I was gonna put a repair coupling &sweatvot but then I thought about it&figured the solder would melt out.I know my flux welder wont work.I thought about about using exhaust cement&a pop can wrapping it up with repair fabric &hose clamps...I can do that as a last resort but would like to weld it some how...I dont have a clue what Im doing here.PLEASE HELP!

Hmm, could you sand it, give it some teeth and put a sleeve over it, like a copper or brass plumbing straight coupler or elbow from Lowes, with a bunch of liquid steel or aluminum, the tube stuff? Maybe sleeve it with some JB weld? Not sure what heat resistance JB has.

Then I would sleeve it and use liquid steel with the tube roughed up good to promote adhesion and let it cure well. Or work it a little more with a penetrating agent, get the tube out and replace it.

I think brass can be brazed if you have an oxygen-acetylene torch. If you know somebody that does heating and a/c they should be able to do it for you in about 5 minutes. Most a/c systems are brazed to hold up to higher temps and pressures than solder. If you still have any radiator repair shops near you they might be able to do it too. If you want to do it yourself a weld shop will be able to sell you what you need. just put a sleeve over it and it is a lot like soldering pipes together but at much higher temps. It is easy to burn thru your pipe so practice a bit first.

As far as jb weld I used it on exhaust once, it smoked and smelled awful for weeks but was still holding a couple years later when I junked the car. I wouldn't do it again though, that smoke was bad.
