Explanation:JH-SJ301 is the agglomerated flux produced by imported technical know-how and equipment of Swiss Qlicon Welding Industry Company, its former product name is OP143.
JH-SJ101 is a calcium-silicon type neutral flux,alkalinity around 1.0.It is gray and black round grain,with grain size around 2.0~0.28mm.It can be operated with AC and DC,the wire shall be connected to positive pole when applying DC.It has steady arc,nice weld formation,and easy in slag removing,as well with perfect deposit metal welding mechanical properties.It suits various welding conditions, with short slag, and no flow appearances.
Applications:Accompanying suitable wires (H08A,H08E,H08Mna,etc.), mainly applied in the welding of normal low carbon steel and some low alloy steel (like Q235,20g, X65,etc.) structure and the submerged welding of boiler pressure vessels, ships,pipe lines,etc.Its deposit metal owns perfect impact toughness.It suits the submerged welding with multiple layers, double sides single layer,and multiple wires.
Chemical Composition of Flux
Mechanical Properties of Deposit Metal
Points of Attention：
1 The fluxs to be dried 2 hours in 300℃~350℃.
2 De-rusting, water and oil cleaning ,as well other impurities removing of the work be done before welding.
