E2209-16

AWS A5.4 E2209-16
Characteristics and Applications:
E 2209 is designed to weld duplex stainless steels such as UNS 831803(Alloy 2205). lt providesexcellent pitting corrosion resistance，stress corrosion resistance and crack resistance. It is suitable forwelding application of heat exchanger, chemical equipments and pipes.
Notes on usage:
1.Be sure to clean up the contaminations on the base metal, groove and pass to pass with stainless steelbrush.
2.Maintaining short arc length as possible is highly recommended.While welding with weave method, movingrange should be controlled within 2.5 times of the wire's dia.
3.Dry the electrodes at 250~300℃ for 60 minutes before use. Take out a batch of half day consumption andkeep in the environment at 100~150℃ during welding process.
4.Use lower current to prevent from crack and minimize base metal dilution.
