Characteristics:
LKE-NiCu-7 is a low hydrogen type covered electrode. Excellent weldability and stress corrosion resistance are obtained.
Applications:
It is suitable for Monel 400, valves, pump and propeller of petrochemical plant.
Notes on Usage:
1.Dry the electrode at 350-400℃oc for 30-60 minutes.
2.Use small amperage and keep the arc as short as possible.
3.Flat position welding is recommended
