Applications
Supercored 81-K2 is used for the welding of low temperature service steels in the construction of LPG and LNG storage tanks.
Characteristics on Usage
Supercored 81-K2 is a titania type flux cored wire designed for all position welding 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.
