Characteristics and Application
AWS A5.4 E309L-16 Welding rods, welding electrode The weld metal contains more Cr, Ni than 308/308L. Suitable quantity of ferrite in microstructure allows it to have excellent resistance to hot cracking. It is designed for dissimilar metal welding of joining mild steel to stainless steel, hardening alloy steel and steel with poor weldability. Proper base metals include stainless steel plate, steel strip, steel tube, heat transfer tube, pressure vessel, steel bar, casting and forging.

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.
