Key note:

Storage Condition

Dew point of Consumable Gas: – 60 Deg

Filler material must be stored in an area with controlled temperature and humidity.

MMA Consumables

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.

TIG Consumables

EB INSERT (SEE TERMS AND DEFINITIONS)

Nitrogen will not be used for Ni,Ni-alloys and Mild Steel

MIG/MAG Consumables

Electrode coating with Copper (for electric pick-up) can cause Cu-contamination in welds

“Cast” & “Helix” terms used for checking the quality of wire

FCAW Consumables

Potassium & Sodium used for Arc stabilization and Slag formation.

SAW Consumables

• Hygroscopic ~ absorb the water
