GEEFLUX 544 X EM 12K

CLASSIFICATION : AWS/SFA 5.17M:F7A4 EM 12K

CHARACTERISTICS :

Agglomerated rutile alumina type flux recommended for single and multilayer welding of structural steels. The flux is resistant to porosity and slag detachability are excellent. The consumptions of flux is small and usually is about 1.1kg for 1.0kg of wire

APPLICATION :

Structural steels

IS : 2062 or equivalent

H-beams, ships , pipes, general fabrication

Storage tanks, etc.

For welding ASTM A573 Grade 70 steel.

SPECIAL INSTRUCTIONS:

  • Dry the flux at 3000C –3500C for minimum 60mts before use.
  • Pay attention to welding voltage. Excess voltage causes deterioration of joint properties.
  • Add fresh flux periodically to prevent weld defects and bead appearance 

CURRENT CONDITION: AC/DC(+)

PACKING SPECIFICATION : 25.0 Kg in a polythene coated gunny bag.
