AWS A5.4 : E310
▶︎ Characteristics:
LKE-NiCrFe-1 is a low hydrogen type covered electrode. The weld metal provides excellent machining property, good heat resistance, good corrosion resistance, good toughness especially at low temperature.
▶︎ Applications:
It is suitable for the welding in all position of INCONEL ,INCONEL to stainless steel ,INCONEL to low alloy steel or stainless steel to low alloy steel.
▶︎ Notes on Usage:
1. Use small amperage as possible and keep the arc as short as possible.
2. Dry the electrode at 350-400°C for 30-60 minutes.
