설명
특성:
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.
애플리케이션:
It is suitable for welding of ASTM B163/166/167/168,Inconel600,cryogenic steels, martensitic to austenitic steels, dissimilar steels etc.
사용 시 참고 사항:
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.
