AWS A5.9 ER309LSi

  • An improved version of ER309L with the addition of silicon (Si) to its composition.
  • Designed for welding dissimilar metals, particularly for joining austenitic stainless steels  to carbon and low-alloy steels
  • The addition of silicon (Si) in ER309LSI improves the weld metal’s fluidity and wetting characteristics, resulting in better bead appearance and increased penetration.
  • Provides excellent corrosion resistance, making it ideal for applications in corrosive environments. The welds retain their corrosion-resistant properties, ensuring the integrity of the welded structure.
  • It is versatile and suitable for a wide range of applications that involve welding austenitic stainless steels. The improved wetting  makes it suitable for high speed welding.
  • It is commonly used in industries such as petrochemical, food processing, power generation, and other applications that involve high-temperature and corrosion-resistant welds. It is particularly valuable for joining stainless steel to carbon steel or for overlaying stainless steel surfaces with a corrosion-resistant layer.
  • Shielding gas for MIG: 98%Ar+CO2 , for TIG: 100%Ar
    • MIG:    0.8-1.6 (mm) /    0.030″,0.035″,0.045″,1/16″
