AWS A5.34 ENiCrMo3T1-4

Characteristics and Application

AWS A5.34 ENiCrMo3T1-4 Flux Cored Arc Welding Wire is the rutile high nickel alloy flux cored wire. Applicable for Inconel 625 dissimilar welding, 5% Ni and 9% Ni plate low temperature tank welding with a good Welding slag detachability, stable arc, minor spatter and good heat resistance. It has good impact toughness at -196℃, excellent corrosion resistance and oxidation resistance, especially resistance to corrosion and chloride-induced stress corrosion cracking.  Application include furnace equipment, petrochemical, power plants, marine and marine environments, LNG(liquefied natrual gas) storage tank.

Notes on usage:

1. Moisture, rust stains, oil containment on the base metal must be fully removed before welding to prevent the formation of porosity and cracks
2. Use 80%Argon and 20% CO2 shielding gas. 

3. Keep shielding gas rate at 15-25 l/min. The best gas flow rate is 20 l/min.

4. Preheating is not required. Inter-pass temperature at 80℃—100℃.

5. Transport and storage should pay attention to moisture.
