I am currently working on developing a Procedure Qualification Record (PQR) for Duplex Steel. In the process, I conducted welding using the base material SA 790 (UNS:32205) and utilized two different filler wires: ER-2594 and ER-Nicr-Mo-14 for different coupons. Size of the coupon 6" Thick:10.97 mm.
However, I encountered a concern during the corrosion testing phase, as per ASTM A923-03 standards. Both test materials failed the corrosion test. I'm seeking guidance from the experts in this group to understand the possible reasons for the failure and to explore potential solutions or alternative approaches.
If anyone has experience with similar issues or insights into the matter, I would greatly appreciate your assistance.
