GFC 2209, E2209T1-1/4
CLASSIFICATION
AWS/SFA 5.22: E2209T1-1/4, EN ISO 3581: E 22 9 3 N L B
DESCRIPTION
GFC 2209 is a rutile type flux cored wire for all position welding with CO2 & mixed gas. As deposition rate is higher than solid wire and MMA electrode highly efficient welding can be performed.

TYPICAL APPLICATIONS
• Off-shore platform pipe work, pipelines transporting chloride bearing products or sour gas and process vessels for chlorine environments.
• ASTM A 182 Gr. F 51
• USN S 31803
• DIN 1.4462
• Chemical and petrochemical process industries.
SPECIAL INSTRUCTIONS:
• Proper preheating (50 - 150°C) and interpass temperature must be adopted in order to release hydrogen which may cause crack in weld metal.
• Both 100% CO2 and mixed (Ar + 20-25% CO2) gas are useful.
SHIELDING GAS : CO2 / (Ar + 20-25% Co2)
