    Suitable for civil construction, steel frame, steel pipe hook, chimney, pipe and other structural parts of outdoor welding.
    The standard we met: GB/T10045 T 49 Z T7-1 N A , AWS A5.20 E71T-A & A5.20M E491T-7, ISO17632-A:T42 Z Y NO 1, ISO 17632-B:T49 Z T7-1 NO A, JIS Z3313 T49ZT7-1NA.

    B1

    What are the
    characieristics?

    The melting drop is fine melting drop transition or spray transition.

    With good penetration depth, good wetting degree and fast melting filling speed.

    Low sulfur content of weld metal, good crack resistance.

    Small diameter welding wire can be used for full position welding.
