Introduction: JQ.SJ101 is a kind of fluoride-basic type sintered flux. The alkalinity is approximately 1.8. Gray round grains. The granularity is 2.0~0.28mm (10~60 meshes/inch). When welding, the arc has stable burning. It has good slag detachability and beautiful appearance of weld. The deposited metal has higher low temperature impact toughness. AC/DC. When welding with direct current, the wire should be connected to the positive terminal.

Uses: If used together with appropriate wires (such as H08MnA, H10Mn2, H08MnMoA, H08Mn2MoA, etc.). Able to be used for welding many kinds of low-alloy structural steel, such as hulls, boiler pressure vessels, pipelines, etc., they can be used for multi-layer 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.
