描述
特性：
LKE-7018-1H4 is a low hydrogen type electrode for the welding of 490N/mm² grade high tensile steel. It is designed for single and multiple pass applications. The welding can be done with good appearance, stable arc and low spatter. With excellent mechanical properties, impact value at temperature of -46°C and low diffusible hydrogen.
應用：
It is suitable for welding of low alloy steels, medium carbon steels, heavy steel plates, cast steels, aluminum killed steel of LPG and especially for welding of steels with poor weldability.
使用注意事項：
1.Dry the electrodes at 350-400°C for 1-2 hours before use.
2.Keep the arc as short as possible to prevent moisture pick-up.
3.Take the back-step method to prevent blowholes at the arc starting.
