Description:
J9.SJ102 is a fluorine-alkali type high-basicity sintered flux with a basicity of about 3.5. The flux is round particles with a particle size of 2.0~0.28mn (10~60 mesh). It has excellent welding process performance, stable arc combustion, excellent slag removal performance in the groove, beautiful weld formation, and high low-temperature impact toughness of the molten metal. It is suitable for DC welding, and the welding wire is connected to the positive electrode.
Application:
With appropriate welding wire (such as H08MnA, H10Mn2, H08MnMOA), it can be used to weld a variety of low-alloy structural steels, high-strength hull structural steels, and pressure vessel steels. It can be used for multi-pass welding, double-sided single-pass welding, multi-wire welding, and narrow gap submerged arc welding.

Notes:
1. The flux must be baked at 300~350ºC for 2 hours before use.
2. Before welding, remove rust, oil, moisture and other impurities on the weldment.
