SUBMERGED ARC WELDING FLUX
Name of products: Agglomerated flux SJ302
Silicon- Calcium Agglomerated flux
Execute standards: GB/T 5293-1999 GB F5A2-H08MnA;
( Equivalent to AWS F7A2 -EM12K; AWS F7A0 – EL12; )
Description of flux :
Agglomerated flux SJ302 is a kind of agglomerated flux type Silicon and Calcium with ball form granular of brown, Bllw≈1.1;about 10 – 60 mesh in size. It is suitable for AC or DC(+) power. It has stable ARC, neat bead appearance and shows good weld-ability. The slag detachability is better than that of SJ301. it is suitable for the girth welding of different diameter. This flux has good anti-humidity absorption. The anti-cracking property is better than other flux with good impact toughness.
Application of Welding Flux:
In combination with wire EL8, EM12K, EA1 and etc. this flux is suitable for the welding of structures, boilers, pipelines and etc.

Guideline for usage:
1.--- Dry the flux at 300℃ – 350℃ for 2 hours before use.
2. ---Completely remove Rust, Oil and Dirt from the groove surface prior to welding.
NOTE:
Agglomerated flux use a binding agent to hold materials together, are baked, and broken up. Agglomerated fluxes are easier to customize for an application, and can provide various alloying elements needed for welding.
