GEEFLUX 544 X EH 14

AWS/SFA 5.17 : F7A(p)5EH 14
Fluoride -basic type
Welding flux for submerged -arc welding process

CHARACTERISTICS :

Geeflux-544 is an agglomerated fluoride-basic type flux, perferably used for welding of high-strength fine grain structural steels, as well as cryogenic steels and steels resistant to ageing. Owing to its neutral behaviour as to the pick-up and burn-out of the elements silicon and manganese, it is advisable to use wire electrodes having a lower silicon and  higher  manganese content. Geesaw 544 flux is suitable to be employed for welding offshore components. The weld metal produced in combination with corresponding wire electrodes meets high toughness requirements at subzero temperatures. Welds are uniformly shaped, without constrictions and undercuts. The flux is suitable to be used on either DC, positive pole, or AC up to about 1000A.

Damp flux must be redried at 300-3500C

TYPICAL APPLICATION :

  • Welding of fine grained medium tensile steel such as BS:EN10028-3–All grades to P460NL1, A516 grade 60/70
  • Pressure vessels, pipes, forgings etc.
