설명
특성:
LKE-8018-C1 is an iron powder low hydrogen electrode for the welding of low temperature service steel. Good impact value can be obtained at -60°C. The weld metal contains 2.5%Ni, that will be suitable for the welding of low temperature service. The welding bead can be done with good X-ray soundness, equal fillet leg size, high efficiency, and nice bead appearance.
애플리케이션:
It is suitable for high carbon steels, low Mn alloy steels, high tensile steels, cast steels, low temperature steel pipes, aluminum killed steels. Its features make the product being applied to shipbuilding, structural fabrication, bridge structure, pressure vessel.
사용 시 참고 사항:
1.Dry the electrodes at 300-350°C for 60 minutes before use.
2.Do not exceed the proper range of current, otherwise impact value will decrease.
3.Take the back-step method at the arc starting.
4.Keep the arc as short as possible.
