Description
Characteristics:
LKE-8016-G is an electrode for the welding of 550 N/mm² grade low-temperature service steel. With good toughness can be obtained at -45°C due to containing of 0.8%Ni.
Applications:
It is suitable for welding of Aluminum Killed Steel use at LPG tanks including high-carbon steel, low Manganese alloy steel, cast iron, steel pipe for low temperature service, pressure vessel, etc.
Notes on Usage:
1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Do not exceed the range of recommended because over heat input might decrease the impact value.
3.Keep the arc as short as possible.
4.Thick plate should be preheat at 50-100°C
