    Welding flux SJ302

     

    Introduction:

    SJ302 is a kind of silicon-calcium type medium sintered flux, B//W=1.0-1.1, MESH 10-40(2.0-0.45mm).

    Either alternating or direct current can be used. The welding bead shapes well and the welding slag is “short slag”.

    And the welding seam has fine toughness and moisture and crack resistance.

     

    Application:

    When applied to welding wires (H08A or H08MnA), it can weld boilers, pipeline steel and common steel.

     

    Attention:

    1.The oil soil, iron rust and other foreign substances must be removed from the welding joint.

    2.The welding flux must be baked under 300-350℃ for 2 hours before welding.
