Dew point of Consumable Gas: – 60 Deg
Filler material must be stored in an area with controlled temperature and humidity.
Core wire made by Rimming steel
Weld properties controlled by covering Flux
Silicon (De-oxidizer) added to Flux to avoid the Porosity inhibited by rimming steel
Flux types comparison:
Flux types identification:
Impact test energy as per EN ISO 2560:
Tensile strength or Yield Strength
SS – ELECTRODE SMALLER THAN CS ELECTRODE BECAUSE OF LOWER ELECTRIC CONDUCTIVITY.
EB INSERT (SEE TERMS AND DEFINITIONS)
Nitrogen will not be used for Ni,Ni-alloys and Mild Steel
Electrode coating with Copper (for electric pick-up) can cause Cu-contamination in welds
“Cast” & “Helix” terms used for checking the quality of wire
Potassium & Sodium used for Arc stabilization and Slag formation.
- Hygroscopic ~ absorb the water
