NST TIG Duplex 2209

TIG-rod for stainless steel welding.

AWS: A5.9 ER 2209
EN ISO 14343: 2009 22 9 3 N L

General description:

NST TIG Duplex 2209 is used for welding Duplex materials such as SAF2205, EN 14462 and similar. Normally Argon or Argon/N2 mix is used as the shielding gas. The TIG-rod is used for manual welding of both pipes and plates. Level of gas flow is dependent upon TIG-rod diameter and specific application. The balance between Austenite and Ferrite in the weld metal will depend upon welding parameters, choice of gas and cooling rate. The rod is also suitable for welding of corrosion resistant and stainless materials against Duplex materials and also for welding ‘Lean’ Duplex grades. The TIG-rods are supplied colour coded in yellow with the AWS designation embossed, according to the requirement of the NORSOK standard. ”Purity” is the keyword when welding high alloyed materials. Impurities in the weld, will cause porosity. Welding of pipes require use of purge gas in order to ensure a stainless root face of the weld. Inter-pass temperature should not exceed 150°C, and heat input should not exceed 1.5kJ/mm.
