説明
特徴
LKE-NiCrMo-3 is a nickel based low hydrogen type covered electrode which contains Mo and Nb. The excellent heat resistance and corrosion resistance can be obtained. It is suitable for chemical plant, nuclear reactor, Inconel 625, 9%Ni steel and dissimilar metals welding.
使用上の注意
1.Dry the electrode at 350-400℃oc for 30-60 minutes before use.
2.Use small amperage and keep the arc as short as possible
