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 250-300 °C for 60 minutes and keep at 100-150 °C before use.
2.Use lower currents for dissimilar metals welding.
3.Keep the arc as short as possible.
