Description
Characteristics:
It is design for welding duplex stainless steel such as 2205.With good resistance to intergranular corrosion, pitting and stress corrosion cracking especially in environments containing H₂S and chlorides.
Applications:
It is suitable for welding of 22%Cr duplex stainless steel.
Notes on Usage:
1. For TIG process, use DC(-) current .
2. For MIG process, use DC(+) current.
3. 98%Argon – 2%O₂ shielding gas is recommended in MIG process.
