Description
Caractéristiques :
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.
Applications :
It is suitable for welding of ASTM B163/166/167/168,Inconel600,cryogenic steels, martensitic to austenitic steels, dissimilar steels etc.
Notes sur l'utilisation :
1.Dry the electrode at 350-400°C for 30-60 minutes.
2. utiliser un faible ampérage et maintenir l'arc aussi court que possible.
3.Keep the interpass at 150°C.
4.Take back-step method to prevent blowhole at arc starting.
