Purpose
JQ.SJ102GQ
12470-2003
Working with proper welding wires (such as H10Mn2, H08MnMoA and H08Mn2MoA) it can be used for welding variety of low-alloy structure steel, higher strength hull structural steel and low temperature pressure vessel.
JQ.SJ102Ni
F5A6-H10Mn2
F7A8-EH14
Working with proper welding wires (such as H10Mn2,H08MnMoA and H08Mn2MoA ) it can be used for welding variety of low-alloy steel, higher strength hull structural steel and low temperature pressure vessel.
JQ.SJ201
F5A4-H10Mn2
F7A4-EH14
Working with Ho8MnA, H10Mn2, H08MnMoA, H08Mn2MoA and other welding wires it can be used for welding variety low-alloy steel, especially suitable for welding thin bevel narrow gap of heavy plate.
JQ.SJ301
F6A0-EM8
Working with the right welding wires (H08A, H08MnA, and H08MnMoA) can weld ordinary structural steel and the steels that are used in boilers, pipelines.
JQ.SJ303GS
F4A2-H08A
F6A0-EL8
Welding with proper welding wires (such as H08A, H08MnA, and H08MnMoA) it can be used for welding low carbon steel and low-alloy steel structure such as ship, boiler, pressure vessel, especially suitable for high-speed welding thin plate.
JQ.SJ402
F5A0-H08A
F7AZ-EL8
Working with H08MnA welding wires can be used for welding low carbon steel and some low alloy of thin steel plate and medium steel plate. It is used for welding metal structure of locomotive and mining machinery, especially suitable for high-speed welding on thin plate.
JQ.SJ501
F6AZ-EL8
Working with proper welding wires (H08A,H08MnA and H08MnMoA) can weld the structures made of low-carbon steel and low alloy-steel such as ship, boiler, pressure vessel; the flux working with proper wires can perform very well in the situation that requires high-speed welding on the thin steel plates.
JQ.TG50
ER50-6
ER70S-6
Used for all-position manual tungsten argon arc backing weld and arc welding on pipelines, and both can produce satisfactory welded joints. It can be used for welding carbon steel and some low-alloy steel.
JQ.TH550-NQ-Ⅲ
Using with sintered flux JQ.SJ101, it can be applied for temperature-resistant steel of tensile strength 550N/mm2.
JQ.YJ501-1
E501T-1
E71T-1C
Used for welding structures made of carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa. Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery etc.
