Hi everyone.My Name is Magno Rodrigues, I'm new here. I would like your help to solve a question.
As we know, some people use nitrogen instead of argon as a backing gas on stainless steel 304, 316 welding
In case of 900 series, 904l specifically, the WPS order to use a 100% purity argon.
I have read some articles, but not about the situation above.
My question is: Can be used nitrogen istead of argon to purge 904l Stainless Steel? If not, Why?
Thanks
