What is the welding process of duplex stainless steel 2507? What electrode?
The brand of welding rod is: 2209. The electrode must be dried before welding. The drying process is 2 hours at 250 C, and the welding rod must be insulated with electrode.
Downstairs the wrong answer, the 2209 electrode is welded with 2205, 2594 is the 2507 welding, argon arc welding process is more convenient, I can send you 2594 of the penguins look, in addition, the use of simple welding rod imports, domestic quality is too unstable. Need to contact me
