AWS A5.29 / ASME SFA5.29 E81T1-GC
JIS Z3313 T55 2 T1-1 C A-U H10
Applications
All position welding for construction machinery, bridge structures and storage tanks.
Characteristics on Usage
GSF81T1-GC is a titania type flux cored wire applicable for all-position welding by 100% CO₂ shielding gas has good weldability and low spatter levels and good bead appearance. Slag covering is uniform and easy to remove.
Notes on Usage
① Proper preheating (50~150°C)(122~302°F) and inter-pass 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 Use 100% CO₂gas.
