Product Description

LJ-SJ101G
Conforming   to:GB/T5293   F4A4-H08MnA    F5A4-H10Mn2
Equivalent   to:AWS-A5.17    F6A4-EMI2K   F7A4-EHI4

Description:
SJ101G is used for special agglomerated flux for buried arc of X60--X70 grade pipes materials.The basicity is about 1.8,white round particles,and the grain size is 2.0--0.4mm(10-45 mesh).It can be used for both AC and DC,and the welding wire is connected to the positive pole in DC.The arc combustion is stable,slag removal is easy,and the weld seam is beautifully formed.The weld seam has high impact toughness at low temperature.Due to the special production process,the flux has good moisture resistance, and the loose specific gravity of flux is small.In the welding process,the flux consumption is small.
Usage:
Combining with appropriate wires(H08C,H08MnA,H10Mn2,H08MnMoA,HO8Mn2MoA),it can weld a variety of pipe steels,such as X52,X60,X65,X70,etc.,and  can  also  be  applied  to  multi-layer welding,double-sided single pass welding,multi-wire welding and narrow gap submerged arc welding.

Remark
1.Before welding,fluxes should be baked for two hours at 300-350ºC

2.The oil soil,moisture,iron rust and-other foreign substances must be removed from the   welding   joint.
