説明
特徴
LKE-309MoL is a rutile electrode use as a buffer layer in welding acid resisting clad steels. With crack resistance and corrosion resistance at the high temperature due to higher Mo content.
アプリケーション
It is suitable for dissimilar metal welding of joining mild steel to stainless steel and steels difficult to weld.
使用上の注意
1. Dry the electrodes at 250-300oC for 60 minutes and keep at 100-150oC before use.
2. Use lower currents for dissimilar metals welding.
3. Keep the arc as short as possible.
