I have some Christmas presants I want to build and have some questions before I build them. Does anyone know if you can fuse copper or brass together with a TIG welder???? I have fusion welded stainless, mild steel and aluminum , but never copper or brass. I want to do about 20 ga copper and it is just for looks not any thing structeral. Is there a certain type of filler rod for copper or brass?? Or is it just easyer to solder or braze it together??? No its not for a smoker Sad I wish it was they are more fun to build... Thanks for all your help Caleb

The heat is a little too concentrated for Tigging brass, it will just curl up and run away from the puddle. You will make out better with brazing and some brass filler rod. I like brazing ornamental stuff with brass filler, it flows real nice. Smile

I will go with Jonny for sure on this one. I haven't done much Tig work but I love to Braze copper.

If it is for looks only, you could also solder it. You could also solder the brass to the copper if needed.
