GEMINI - GL 26

LOW CARBON WELDING ELECTRODE

TCVN 3223–2000 E432R

TCVN 6259–6: MW2

AWS E6013/ JIS D4313

 Characterics on Usage:      
   
  • GL 26 is a high rutile type covered electrode for all position welding. 
  • GL 26 is suitable for Carbon steel and low alloy-steel such as vehicles, machines, and surface dressing of heavy steel structure.. 
  • It's easy-slag-removable. few blowhole, smoke and spatter. Its weld bead is smooth, shinny; the arc is soft; the re-striking is good and penetration is shallow. The quality of weld's joint is unchanged when using lower current..

 Usage introduction: 

  • Pay attention not to exceed the range of proper currents. Welding with excessive current not only lowers X-ray soundness, but also causes increase of spatter, under-cut and insufficient slag covering.
  • Dry the electrode at 70-100oC for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosity.
