Partners,
I have to repair a pump casing in our shop, the casing is Duplex construction (ASTM A890). I need to know the welding procedures and the rod type I have to use? I have experience with Ni-AL-Brz, 316SS and carbon steel, but this is the first time that I have to repair a SS Duplex part.
Can somebody help me (sgabayq@cantv.net) ? English/spanish
