설명
특성:
LKE-7016 is a low hydrogen type electrode for the welding of high tensile steel. The welding can
be done with stable arc, less spatters, good slag removability, good slag covering and good X-ray soundness.
애플리케이션:
It is suitable for low alloy steels, medium carbon steels, heavy steel plates, cast steels and steels of
poor weldability. Due to good X-ray and mechanical properties, LKE-7016 is used for skill testing and competition
by choice.
사용 시 참고 사항:
1.Dry the electrodes at 300-350oc for 60 minutes, and keep at 100-150oc before use.
2.Take the back step method to prevent blowholes at the arc starting.
3.Keep the arc as short as possible.
