what's the proper welding rod to use when doing this? ive always used stainless flanges but now i have a project where the customer is supplying a mild flange. ive been messing around on scrap stuff and the standard mild rod i use seems to not mix well and the stainless seems likely to crack. any help would be apreciated because i know some of you guys use mild flanges with your turbo manifolds.

 

I believe it is 309 rod..

 

I use 309.

 

Use 309
Someone told me 312 is also good for stainless to steel aplications..
Never used it though.

 

309L is what is typically used.

 

cool, i tried with the 316 rod i have, im going to pick up some 309 tuesday. thanks guys
