     ACCORDING WITH GB/ T 10045 E501T-1L
    CORRESPONDING WITH AWS A5.20 E71T-1J
    JIS Z3313 YFW-C502R


    Introduction & Characteristics:
    FRW-71Ni is a titania type flux cored wire whose weld metal contains Ni a little and has the same usability and efficiency as those of FRW-71 in all-position welding by CO2 shielding.The weld metal makes excellent impact value at temperatures down to -40℃ under as-welded condition.
    Typical application:shipbuilding,offshore,bridge,pressure vessal and general fabrications.

    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.
