has anyone here had experience welding or brazing EGR tubes? is it possible? i'm thinking they may just melt like butter, but thought i'd ask around first.

Hi Troyco
On a 4.6 liter engine for the effort in removing the EGR tube and the cost of a new one it isn't worth welding but yeah I welded mine while awaiting a new one

sorry, i should've probably explained a little better why i'm looking to do this, i'm installing headers, so i'm gonna have to piece together at least a couple of tubes to make it work with the mustang's driver's side EGR bung. did you weld it or braze it?

You braze with a lower temp so you don't have to worry so much about burning holes in things.
Just make sure your rod melts at a lower temp than what your working on, lolPete ::::>>> resident LED addict and CFI defector LED bulb replacements

Hi Troyco
I welded mine with a MIG welder but the tube was so thin I had it on the lowest setting and had to just sort of spit the weld on or it would blow a hole.

I would imagine even soldering could work so long as your solder has a higher melting point than the temperatures the part would be subjected to. Modern lead-free solder is a major pain to work with, though ... lots easier to use that coated Lincoln brass rod from Lowe's, provided you have a suitable torch.2012 Mazda5 Touring | Finally working on the LTD again!

thanks guys. i've done alot of brazing in the past with old coat hangers, worked well. and cheap. but i'm thinking that'll probably not work in this case. i've also thought of solder, but like 1987 cp stated, it's a PITA to work with the lead-free stuff, and i'm afraid of it melting off. i guess i'll just have to experiment.

If you have access to one I would use a tig. The key to torch and tig welding really thin shit is to make sure your filler rod is thinner than your base metal.
Brazing would work fine too.
You might be able to mig it sucessfully with an .020 wire or .023 wire. Also try using some of that heat sink compound to pull some of the heat away.
I wouldnt solder because of the low melting point of the solder and using it in an exhaust system. Would most likely crack too after periods of heating and cooling.
