AWS A5.4 : E310
▶︎ Characteristics:
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.
▶︎ Applications:
It is suitable for dissimilar metal welding of joining mild steel to stainless steel and steels difficult to weld.
▶︎ Notes on Usage:
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.
