설명
특성:
LKE-12018-G is a low hydrogen electrode for the welding of 830 N/mm² grade high tensile steel. With excellent crack resistance, good mechanical property and bead appearance. It is provided with good arc and easy slag removal.
애플리케이션:
It is suitable for welding of heat treatable low alloy steel such as SCM21/4 Cr-Mo steel,SNCM8 Ni-Cr-Mo steel. Proper base metals are also including forging cast iron(ASTM A486 Gr.120/A508 Gr.5a.4a),pressure vessel steel plate (A543 Gr.B3C3),ect.
사용 시 참고 사항:
1.Dry the electrodes at 350-400°C for 60 minutes and keep at 100-150°C before use.
2.Preheat the plates at 150-200°C is before welding.
3.Keep the arc as short as possible.
4.Take the back-step method at the arc starting to prevent blowholes.
