Hi, Martin. Thanks for the reply. The thing I'm working on is more onto the structural side (not really structural as in building btw). I've read the AWS code on steel and stainless steel, but since it's a design side question, not a fab side question, it doesn't help. But yes, I'm aware I can use FCAW, SMAW, GMAW, TMAW for the work, and I"m aware the the type of weld, and joint types, and even shieding gas. Application for me is still quiet open. It is just a general knowledge type of question.
