Characteristics and Application

AWS A5.4 E309LMO-16 Welding rod, welding electrode  is superior to 309/309L in crack resistance and corrosion resistance et the high temperature due to higher MO content. Low carbon content of weld metal makes it suitable for dissimilar metal welding of joining mild steel to stainless steel and reducing inter-granular corrosion.

Notes on usage:

1. Clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush.
2. Maintain short arc length. Moving range should be controlled within 2.5 times of the wire's dia when you are welding with weave method.
3. Dry the electrodes at 250—300℃ for 60 minutes before using. Take out consumables for half day consumption and keep in the environment at 100—150℃ during welding process.
4. Use lower current to prevent from cracking and minimize base metal dilution.
