Applications
Supercored 81MAG can be used in oil and gas construction, pipe, and offshore structures.
Characteristics on Usage
Supercored 81MAG is a titania type flux cored wire to be used with Ar+CO₂gas mixture shielding.
This provides excellent notch toughness at low temperature, not only as-welded but also stress relieved state.
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 Ar+20~25% CO₂gas.
