GFC 111K3

SPECIFICATION : AWS/SFA 5.29 : E 111T1 K3C JIS Z3313 T762T1-1MA-N3M2 H5

CHARACTERISTICS :

  • Wire is a titania type of flux cored wire for all-position welding.
  • It provides smooth arc, low spatter levels, good weldability and good bead appearance.
  • It provides excellent impact values at low temperature.

TYPICAL APPLICATION :

GFC 111K3 is designed for welding of 760 MPa high tensile steel with outstanding mechanical properties.

The typical applications include high tensile steels that will be used a low temperature environment.

Diffusible Hydrogen in the weld metal: max 5ml/100g of weld metal.

Notes on Usage:

  • Proper preheating (50-150° C) and interpass temperature must be used in order to release diffusible hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates.
  • Gas flow rate is proper 20-25 L/mm
  • Shielding gas should be used 100% CO2 or Ar+20-25% CO2.
