Product information

Unitor Iduplex-222 is a TIG rod for welding duplex stainless steel grades like WNr.1.4462, UNS 31803. The deposit offers elevated mechanical strength and toughness resistance to stress corrosion cracking. Application areas are similar to those for coated electrode Duplex-325 N, but with the advantages TIG can offer.

Features

  • High mechanical strength and toughness
  • The weld deposit offers elevated mechanical strength and toughness resistance to stress corrosion cracking

Benefits

  • Less possibility for joint failure during operation
  • Large application area as can be used for welding of duplex to mild steel and duplex to stainless steel (AISI304, AISI316L)

Directions for use

The label on each container fully identifies the contents, and also gives basic information on application areas. Complete information on each flux label, and instructions for use are given in the handbook for maritime welders.

  • Use pure argon as shielding gas
  • Ensure low heat input and interpass temperature should not exceed 250°C
  • Ensure good surface preparation i.e., use only stainless steel abrasive discs or brush for grinding or cleaning
