Frequently Asked Questions (FAQ)
What is the recommended shielding gas for Super Duplex TIG welding?
We recommend using Argon with 2-3% Nitrogen to maintain the austenite-ferrite balance in the weld metal and prevent loss of corrosion resistance.
Can ER2594 filler wire be used for welding Standard Duplex (2205)?
Yes, "over-alloying" with Super Duplex filler wire is often preferred to ensure the weld zone has equal or better corrosion resistance than the base metal.
