Sinter Flux

1.Fluxes are generally packed in bags. They should be transported properly to avoid damages. They should be stored in dry rooms to avoid damp that may affect welding quality. 2.Before using them, they should be baked according to the parameters specified in the specification. When baking them, they should be spread on the plates and the thickness should be 50mm at most. 3.Before welding, the impurities on welds of the base metals, such as rust, oil stains, moisture, etc., should be cleared away. 4.When using recycled fluxes, the slag crusts, powder and other impurities in them should be cleared away, and they should be mixed together with new fluxes before using them. 5.When using direct current, DCRP (Direct Current Reversed Polarity), which means the wire should be connected to the positive terminal, is generally used.

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.JQ.SJ101CF4A4-H08MnA F5A4-H10Mn2 F6A4-EM12If used together with appropriate wires (such as H08MnA, H10Mn2, etc.), they can be used for welding hull structures, and also used for welding some key structures like boilers, pressure vessels, pipelines, etc.JQ.SJ101GF4A4-H08MnA F5A4-H10Mn2 F6A4-EM12If used together with some wires like H10Mn2, H08C, etc., they can be used for welding joints of spiral welded pipes of oil and gas pipelines. If used together with H08C, they are especially suitable for welding X65 and X70 spiral welded pipes, and the welding speed can reach over 70m/h.JQ.SJ102F4A4-H08MnA F5A4-H10Mn2 F6A4-EM12 F7A0-EA2-A2If 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.JQ.SJ102NiF5A5-H10Mn2 F5A4-H10Mn2F7A5-EAH14If used together with appropriate wires (such as H10Mn2, H08MnMoA, H08Mn2MoA, etc.), they can be used for welding many kinds of low-alloy structural steel, hull structural steel with higher strength and pressure vessel steel.JQ.SJ105If used together with appropriate wires (such as WM-210 wear-resistant alloy flux-cored welding wire), they can be used for surface overlaying on rollers.
