Explanations: The production of JH-SJ181q is based on the agglomerated flux produced by imported technical know-how and equipment of Swiss Olicon Welding  Industry Company(former product name is OP122)and with refined materials and formula,it is a perfect flux specified in high quality bridge construction,with much more better deposit metal welding technological can charateristics Than JH-SJ101.
　　JH-SJ101G is a soda-fluorine type agglomerated flux,with alkalinity > 1.8 ,It is gray and 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 technological charateristics.
　　Applications:Accompanying suitable wires(H08MnA,H10Mn2,JH-WQ1,JH-WQX2,etc.)mainly applid in the welding of low carbon steel and some low alloy steel
　　(like 16Mn,X70,14MnNbq,WQ490D,WQ490E,Q345,etc.)structure and the submerged welding of boiler pressur vessels,ships,bridges,oil transportation lines,etc.Its deposit metal owns perfect low temperature impact toughness.

　　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.
