Corresponding with AWS F6A4-EM12 F7A0-EA2-A2
DIN BF B165AC12MHP5


Introduction: JQ.SJ102 is a kind of high alkalinity fluoride-basic type sintered flux. The alkalinity is approximately 3.5. Round grains. The granularity is 2.0~0.28mm (10~60 meshes/inch). It has excellent welding performance, stable arc, good slag detachability in the grooves and beautiful appearance of weld. The deposited metal has higher low temperature impact toughness. Suitable for direct current and the wire should be connected to the positive terminal.


Uses: If used together with appropriate wires (such as H08MnA, H10Mn2 and H08MnMoA), they can be used for welding many kinds of low-alloy structural steel, hull structural steel with higher strength and pressure vessel steel. Able to be used for multi-pass welding, single pass welding by both sides, multi-wire welding and narrow-gap submerged-arc welding.

Instructions:
1.The fluxes should be baked under 300~350℃ for 2 hours before using.
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding
