描述
特性：
LKE-NiCrFe-2 is a low hydrogen type and nickel-based covered electrode. The welding can be done in all position with good X-ray soundness and good crack resistance. The weld metal provides excellent mechanical properties which can satisfy the requirements of API and ASME for LNG tanks.
應用：
It is suitable for welding of ASTM B163/166/167/168,Inconel600,cryogenic steels, martensitic to austenitic steels, dissimilar steels etc.
使用注意事項：
1.Dry the electrode at 350-400°C for 30-60 minutes.
2.Use small amperage and keep the arc as short as possible.
3.Keep the interpass at 150°C.
4.Take back-step method to prevent blowhole at arc starting.
