説明
特徴
LKE-11018-G is a low hydrogen electrode for the welding of 760 N/mm² grade high tensile steel. With excellent crack resistance, good mechanical property, bead appearance and lower moisture pick up. It is provided with good arc and easy slag removal.
アプリケーション
It is suitable for welding of TSTE 620V and TSTE 690V high tensile steel.
使用上の注意
1.Dry the electrodes at 350-400°C for 60 minutes and keep at 100-150°C before use.
2.Preheat the plates at 100°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.
