Anyone have experience? I'm headed to the welding store at lunch today but half the time they don't know what they are talking about. I'm welding 321 16g to one incolnel flange and one mild steel flange, thanks.

 

as far as i know, i haven't heard of anyone welding iconel to anything else. stainless to mild would take a 309 rod.

 

I've been reading up a little with the info that burns supplies with their material and they seem to reccomend a higher grade filler than the metal being welded. I normally use the 309l for 304 to mild steel but I was thinking I would have to use a higher grade when welding the 321. And incolnel is pretty common on racecar stuff, the guy I'm building a manifold for use to build all the trd atlantic series engines and says that it welds just like stainless but tends to warp a lot less.

 

I use 312.

 

312 to mild steel or incolnel?

 

I use it for both. It may or may not be best, I am not completely sure, I can say I have never had it fail though.

 

Why dont you just call burns and ask them? Then you will know the correct answer.

 

the rod you want to use is inconel 625.

just wanted to hear from people who had experience with it.

burns said 321 to 321 use 347 filler
321 to mild use 309l
321 to 304 use 308
and 321 to inconel use 625
