    Introduction & Characteristics:
    FRW-81K2 is a rutile and micro-alloyed type flux cored wire designed for all position welding with CO2 shielding gas,and it used in butt and fillet weldign for 550Mpa grade high tensile strength steel.
    Typical application: low temperature service steels in the construction of LPG and LNG storage tanks etc.

    Instructions:

    1.The oil stains and rust on the weldments should be cleared away.
    2. Designed for welding with 100% CO2.
    3. When welding, the gas flow rate is generally 20~25L/min.
