AWS A5.29 / ASME SFA5.29 E81T1-W2C

JIS Z3320 YFA-58W

Applications

GSF.81T1-W2C is designed for the welding of weather-proof steel for example corten A-242 or A-588.

Mainly used for flat and horizontal fillet welding on structural exposed steel usually found on buildings and bridges.

Characteristics on Usage

GSF.81T1-W2C is a titania type flux cored wire which can be used for all welding in conjunction with CO₂

shielding gas.

Notes on Usage

① Proper preheating(50~150°C)(122~302℉) and interpass temperature must be used in order to

release hydrogen which may cause cracking in weld metal when electrodes are used for

medium and heavy plates.

② One-side welding defects such as hot cracking may occur with wrong welding parameter such

as high welding speed.

③ Use 100% CO₂gas.
