EQUIVALENT NORM: AWS A5.20 E71T1-1C-J/ JIS Z3313 YFW-C503R

DESCRIPTION:

·GSF71T1-1C-J is a titanium type and CO2 gas flux-cored welding wire. It can be used for all position welding with excellent welding performances:stable arc,small spatters,good weld shape, and slag easy to remove .It has a satisfactory low temperature impact toughness .And it is good for all position welding.

APPLICATION:

·Suitable for welding medium and thick plates fabricated by mild steel and 490MPa grade high strength steel.Popularly used in flat and horizontal and fillet welds of vessels,machines and bridges,etc.

INSTRUCTIONS:

a.Using CO2 as shielding gas,and its purity must be above 99.98%. 

b.Windshield must be set up in the welding zone,due to gas porosity may be caused by strong wind.

c.The temperature should be kept below 150℃ for multi-pass welding.
