Welding flux HJ350
Conforming to GB/T12470 F48A2-H10Mn2G
Equivalent to AWS F7A0-EH14 JIS YSF-W41
Description HJ350 is defined as fused type fluxes medium-manganese, medium-silicate and medium fluorine elements, color in brown to high yellow, with vitreous granules 8-40 meshes in size. Fluxes are suitable for use both AC and D.C. When applying D.C, filler-wire will be connected to electrode positive (EP). Fluxes have good welding technological behavior.
Field of application: Fluxes match proper filler-wire (i. e H08MnA, H010Mn2, H08Mn2 etc) of which may be use for welding of low-alloyed steel (i. e. 16Mn,15MnVN,15MnV etc) important structures for example: ships, boilers, pressure vessels etc. As required by fine-granule fluxes, they can be used for SAW with filler-wire to serve thin-plating weld.

Remarks
1.Before welding, fluxes need to be baked for two(2)hours at around 300-350°C.
2.Removal of rust, oil, dirt, water, impurities etc in welding-areas.
