Applications
Supercored 81-K2MAG is suitable for single or multipass MAG welding application for LNG, LPG tank, etc. and for all low temperature service steel.
Characteristics on Usage
Supercored 81-K2MAG is an all position flux cored wire for low temperature service steel.
Excellent mechanical properties and low temperature impact toughness. Smooth arc characteristics and very low spatter level.
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.
