Sintered Flux F6A0-EM12

Sintered Flux,AWS F6A0-EM12, is a kind of fluoric-alkali sintered flux, with basicity of 1.8 and the grey rounded grain size of 2.0-0.28mm (10-60 meshes). During application, the arc is stable, and the removal of slag is easy. Welding bead is nice. The deposited metal has good low temperature toughness. The wires can work on AC/DC and must connect to the positive terminal on DC current while using DC.

Application

Sintered Flux, AWS F6A0-EM12 can be working with the proper welding wires (H08MnA, H10Mn2, H08MnMoA, and H08Mn2MoA) can weld multiple kinds of alloy steel structures such as ship body, pressure vessel, boiler, pipeline etc.

Chemical Composition (%)

Reference Current (DC+)

Welding Positions:

Notes:

1. Flux must be baked at 300°C ~ 350°C for 2 hours
2. Impurities such as rust, oil stain and moist should be cleared before welding.
