INTERNATIONAL CLASSIFICATIONS

AWS/ASME A 5.15 E Ni-CI

DIN 8573: E Ni BG 12

ISO 1071: E Ni

NFA 81-342: E Ni BG 12

FEATURES & APPLICATIONS

Used where ultimate machinability is a factor. Also ideal for repairing very thin or eroded sections of cast iron.

  • “Pulsed Arc” high nickel, shallow penetration cast iron minimizes heat affected zone hardening.
  • “Low temperature” gentle globular arc transfer.
  • Excellent arc control in all positions.
  • Weld deposits are extremely soft and machinable due to minimal dilution.
  • Also available in TIG as product code 6043.
