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

    Introduction & Characteristics:
    FRW-71 is a gas-shieled and rutile type flux cored wire of 490MPa high tensile steel.
    It showing us excellent welding performance,soft and stable arc,low spatter loss,easy slag removal,beautiful appearance of weld and high X-ray safety. Higher deposition rate particularly.Suitable for all-position welding.
    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.
