설명
특성:
LKE-NiCrFe-3 is a low hydrogen type covered electrode. The welding can be done in all position with good heat resistance, oxidizations resistance and good corrosion resistance. Good toughness can be obtained at low temperature.
애플리케이션:
It is suitable for welding of Inconel 600, dissimilar steels, heat-resistant steels including ASTM B163/166/167.168.
사용 시 참고 사항:
1.Be sure to clean up the contamination on the plates.
2.Use small amperage and keep the arc as short as possible.
3.Dry the electrode at 350-400oc for 30-60 minutes.
4.Take back-step method to prevent blowhole at arc starting
